Absolutely superb.
Ordered a gaming PC on December 17th and even though I paid for express delivery, I didn't think it would arrive in time.
It arrived 3 days later! The inclusion of Christmas jell
ies in the box was an added nice touch.

FRENCH : Commande d'un boitier Hyte Y70 touch introuvable dans toute l'Europe depuis maintenant plusieurs mois...

CaseKing, un des rares distributeur a avoir eu du stock en décembre, m'a

Certes les paiement en plusieurs fois ne sont pas acceptés par Klarna DE, cependant je peux dire qu'en fonction du prix je commanderais les yeux fermés sur CaseKing !

Order of a Hyte Y70 touch case, which has been impossible to find in Europe for several months now...

CaseKing, one of the few distributors to have had stock in December, delivered it to me in France in just one week! Admittedly, payments in installments are not accepted by Klarna DE, but I can say that depending on the price, I would order from CaseKing with my eyes closed!

Note: Quality check of the package contents not done today, the case looks intact, I will edit the review if otherwise.

I bought a Lian Li brand pc case about 1.5 years ago. The PWM fan cable suddenly broke and I contacted Caseking customer support about it. They responsed me immediately and sent me a new cable without any further quequestions. Thank you for yourhigh-quality service and user-friendliness.

now i have yet to receive my order but originally I had placed a 1 star review as i thought i didn't get any response from customer service. I did not think to check my junk email and when caseking had responded to my review i checked and oh there it was. I read it and they are very nice. I expect to be ordering again when i need something new. Very good prices and customer service compared to other European pc component sellers

Outstanding Service with a Personal Touch

I can’t say enough good things about Caseking. From their excellent product range to their unparalleled customer service, they truly stand out as one of the best PC companies out there in my opinion, especially if you’re based in Europe.

Their customer service is exceptional whether you need help you can contact them through Twitter or by creating a ticket on their website, the team is always quick to respond, professional, and incredibly helpful. They go above and beyond to provide accurate estimates and ensure that every interaction is smooth and stress free.

Caseking has truly set the bar when it comes to providing top notch PC components and accessories. Every product I’ve purchased from them has consistently exceeded my expectations in terms of quality, reliability, and craftsmanship.

Their commitment to offering only the best is evident in everything they sell. Whether it’s high performance GPUs, cutting edge cases, or custom cooling solutions, you can always trust that what you’re getting is fit to the highest standard. They clearly take the time to stock up their inventory, ensuring that every product lives up to the expectations of even the most demanding PC enthusiasts.

It’s not just the products that impress, it’s the attention to detail in packaging and delivery as well. Items arrive securely packed and in perfect condition, further underscoring their dedication to quality.

If you’re serious about building or upgrading your PC and want components that truly deliver on performance and durability, Caseking is the place to go. Their products are a testament to their passion for excellence, and they’ve earned my trust as a go to source for premium PC hardware. Highly recommended!

One of the things I absolutely love about Caseking is their thoughtful touch of including a pack of Haribos in most of the orders I’ve received. It’s such a simple gesture, but it shows they genuinely care about their customers and want to make every purchase a pleasant experience.

A huge thank you to the entire Caseking staff for their hard work, kindness, and dedication. You’ve earned a loyal customer for life! If you’re looking for a PC company that combines quality products with outstanding customer service, look no further than Caseking. Highly recommended!

My 1 stop shop for my custom build

Fast delivery, great prices, got nearly all the parts for my custom build here. I also had to cancel some parts on a second order and I was refunded quickly and with no issues or problems. I will be coming back again for more parts in the future.

Horrible experience with international order

Horrible experience with international order.

I sent in an order on the 3rd of October. It's international, but still within EU space, so I figured - maybe 3-4 days of delay compared to a local purchase? Yeah, buckle up.

I got same-day shipping (offered at checkout) because it was for my nephew's birthday and I hoped it would make it faster. Same-day shipping was ignored - I would come to find out via several calls to caseking that the option is only for clients in Germany - why would you allow it for someone outside Germany then?

The same-day shipping option was with UPS Express, so I checked it also for another reason - UPS would surely have a tracking number. I wanted to keep track of the shipment because in a few weeks I'd be unavailable, and in case it turned out to have delays - I could have it delivered to a friend, or at least rescheduled. I'd have some semblance of control over what happens to it.

This option that I checked and paid for was ignored. The package was sent via some other courier, that they couldn't provide a tracking number for. It's apparently their own trucks or something? I have no idea, but I was assured it's more expensive and safer than UPS Express. As if just because it's more expensive and safer, that means I should shut up and take it, despite wanting something else? And despite no tracking number?

Fact is, this is why I ordered via UPS. I trust UPS. I don't trust their internal trucks. Which I'd find out - I was right not to.

The order was only shipped on the 11th. 8 days after the 'same-day' shipping I paid extra for.

It is now the 18th of October and I just had my last call with customer service. They had contacted me via mail to request some identification number. I expressed I don't know what that is. They gave me some link explaining that shipments that come into the country need to be declared, and they didn't declare it, so they didn't get the number. My shipment HAS NOT YET ENTERED THE COUNTRY AFTER 2 WEEKS. May I take this point in time to make it apparent that a trip via car from my home city to Berlin would take 17 hours - hardly worth waiting 2 weeks for a package.

Considering how they've been constantly disregarding my options, and how they are now requesting me for information that I as a customer cannot possibly give them and it is in the responsibility of their freighter - I requested a cancellation. At this point I don't trust them, so I am also considering contacting my bank and disputing the charge.

Caseking has no idea what they're doing with regard to international shipping. Their website allows you to select (and pay for) options they don't actually offer. Their shipping company doesn't do their job, and then the customer is asked to do it. Their poor customer support people had to take several calls from me to know the status of the package (which would've been avoided if I had a tracking number) and couldn't help with any of my requests, which - I get that their hands are tied, but then just call it /dev/null, not customer service line.

I don't recommend. But I do look forward to Mike (who I saw was quite active around here) coming in with a reply about how he doesn't think it's unreasonable to ask customers how shipping works, or how tracking numbers are for the birds, or how my choices at checkout are just for curiosity and they'll actually be doing whatever they want to my order.

Dear Dragos Zaharescu,

Update: We are refunding the order amount already right now to your payment method.

Original Response:

We are a German company and therefore ship from Germany.

The Romanian Ministry of Finance has decided to implement the RO e-Transport system as of 1 July 2022. RO e-Transport is an electronic system that is used to monitor road transport of goods in Romania. Since 2024, the Romanian authorities decided to extend the law to all types of goods from EU countries, including Gaming PCs. Parcels weighing more than 500 kg or - as is the case with your order - with a goods value of more than ~2000€ (10,000 lei) from and to Romania are subject to declaration and require a UIT code accordingly.

The Romanian ordering party = recipient of goods must apply for a UIT number (meaning you as the customer). The UIT code is a 16-digit combination of letters and numbers. It is assigned when shipments are registered in the Romanian e-Transport system and must be printed on the transport documents during transport within, from and to Romania. The UIT number must be available before the start of transport in Romania and can be applied for a maximum of three calendar days before transport.

That being said, we initially had problems shipping such a large parcel containing a gaming PC in a transport box that's small enough to still count as a regular parcel instead of freight. This is why you were able to order via UPS Express, but we simply could not ship this item internationally with a standard shipping company. Instead, the order had to be switched to shipping via a freight forwarding company (for free, since this costs 6x as much).

All of this resulted in a delay of shipping which is why were were not even remotely able to perform "same day shipping" in this special situation. It is also absolutely normal and common that freight hauling companies do not provide tracking numbers. This is not how hauling works. The so called Avis, meaning the announcement of the delivery done by logistics companies, is then usually done via phone after a few days of international transportation via truck.

We acknowledge that all of this seems to be too complicated to make much sense for private customers and thus we have now requested the parcel to be returned to us. As soon as it arrives and is booked into our system again we will issue a refund via the original payment method.

We learned from this and should be able to actually send out this and similarly large systems via UPS from now on, even if that's too late in your case. I must also apologise for our our recently relaunched new shop software not yet functioning as it should when it comes to international orders and there is nothing to sugarcoat in that regard. We are sorry about that!

Kind Regards
Mike

Very high-quality work done. The PC is built perfectly with attention to detail.

I would like to mention Jeremy, who was always in touch with me and could answer any of my questions. I recommend caseking!

Excellent prices and solid customer…

Excellent prices and solid customer support.

I had some issues with my parts but the problem was on my end. Despite this they offered free shipping back and forth to confirm the parts where in working order which of course they where. Can't rate them highly enough. This is my second build through them having replaced several parts after my intel cpu failed me

PC Parts to Ireland, Highly recommended!

I highly recommend this company!

I ordered multiple PC Parts from CaseKing. Those being:

- A Mid Tower PC Case
- Case fans
- CPU Cooler
- PSU

The purchasing process was very simple and streamlined. Their website has a wide variety of options and was very intuitive to browse.

There were no hidden fee's at checkout, VAT and shipping were shown for each product very clearly.
Products weren't overpriced and were actually quite competitive.

Delivery options were neither minimal nor excessive. I personally went for Basic UPS Shipping to Ireland. One complaint, I did not get any tracking options in my email automatically, however I was able to get the tracking numbers immediately when they were available by going through the support bot which was fine by me. I believe locally they have even more options for delivery.

My products arrived within 5-6 Business Days, so basically after one full week. This shipping was actually faster than Amazon DE from where I had ordered other parts even with Amazon Prime. They arrived later in that week and some even the week after which in total took them 2 weeks. So much for Amazon's speedy delivery they pride themselves on.

In the boxes they threw in the invoice/receipt and even complementary German Candy which was thoughtful. There was no exterior damage to any of the products as far as I can tell, they were boxed well. However I have yet to open the actual boxes and check inside for any damage but I doubt I will find any.

I personally had no reason to contact their customer support but I have heard great things in other reviews.

Overall great experience. No need for any skepticism here, Will definitely shop on the site again and recommend it to all.

Excellent pre and after sales support

I have been a Caseking customer for many years but this was the first time I needed their aftersales support for a warranty matter (which is the most important when rating a computer store). They acted with utter professionalism keeping me updated via email during the whole process and finally replacing the defective product with a new one, within a reasonable time window. A highly recommended company which respects their customers. Thank you guys.

Amazing Service

Ordering process was amazing. The parts came relatively quickly and they are much cheaper than in my home country.

Everything runs silky smooth and I'm having loads of fun with my new PC.

The pc arrived almost half a year ago at this point and I haven't managed to write a review yet because of how much fun I was having while gaming :D

I recommended Caseking to all my friends and you guys definitely got a new customer.

Great company

Ordered parts for a new computer on a Wednesday morning, and it arrived in Ireland the following Tuesday afternoon via UPS Standard. Everything was well-packed and as-described.

They even threw in a packet of sweets! Small enough not to upset my diet, but big enough to make me happy. How can you complain?

Competitive prices and great customer service!

Back in late February I needed to buy myself a nice computer for productivity and gaming tasks and I stumbled Caseking, I figured I could by my Graphics card, Power supply, Processor and RAM from there as their prices was way cheaper than where I lived, it took a bit longer for it to ship than I anticipated however that had nothing to do with Caseking as they shipped it out immediately.

when it has been shipped to my house everything thankfully was working perfectly, however I had realise that the ram I got was incompatible with the motherboard I needed to get for my processor, I hadn’t asked for a refund for the ram until a week later at a Sunday, thankfully they were quick with accepting my refund request and I sent the incompatible ram sticks which was always a good thing to see!

I had also decided to buy thermal paste and my motherboard from Caseking too, and both of them managed to be delivered on a Friday instead of having to wait till Monday this time which was a great thing to see.

when building my PC I had noticed that the heatsink on my graphics card was a bit bent, however this most likely he nothing to do with Caseking and more to do with the Manufacturer or myself, however after loading Furmark it hadn’t reached over 64 Degrees and mostly hovered around 63 after five minutes of load so it’s probably more of a aesthetic issue than a performance one.

TLDR; Customer service was quick with my issues and had pretty good prices for their components, i don’t really understand the amount of 1 star reviews that is given to the company, maybe they are unlucky, however I didn’t went through anything wrong with Caseking, thanks!

It is a shame to be treated like that after a 4000€+ purchase

Edit 2 to answer the "IM ALWAYS RIGHT" guy, because after I buy this kind of product, I do not want the fake customer support to tell me I cannot instal windows.
If you were able to stay quiet and accept blames, which can help you grow up, maybe I would have not answered and showed everyone the bad faith you display:
You said:
→ It is not YOU = "olivier morel" who ordered that PC. The order was placed by another person including the invoice address so that person is our contractual partner, not you.
-I have ordered with my girlfriend account because payment via Amazon. I have 2 houses, I just delivered the new PC to the new house. What is wrong with you? I have sent IDs to trust pilot to proove you are just arguing and lying. That is why Trustpilot put my review back online when you asked to remove it. You do not like the truth, you cannot improve yourself? You will never grow up.
This is a free advice, you see, even if you buy nothing from me. I buy 4000€+ PC and you cannot send me a simple sentence via mail.
This is just a SUPER BAD SUPPORT everybody can understand that. Stop ridicule yourself and your company.

You said:
→ We would've done that ourselves if you had paid for it, which you didn't. We're not going to write lengthy manuals for free.
-"You will probably need to change the PCIe X1 slot 1 and 2 mode to M.2 mode in the BIOS under Advanced."
What a lenghty manual.

-You said:
You ordered a system specifically without an operating system so we're not setting up anything.
YOU TOLD ME: The system is delivered as configured without Windows. We are happy to add Windows. That would be EUR 139.90 for WIndwos 11 home and EUR 159.90 for Professional.
ARE YOU TRYING TO SCAM YOUR CUSTOMERS?
You can instal Windows for free, then activate it later.

-"Looks like" is not equal to "is"
if you have trust issues yourself, this is not my problem, solve it before crying a river.

By replying like that, YOU SHOW your bad support and arguing with customers. Thank you ;)

PS: LCD fan assembly is not even in the good way...
You just ignore Lian LI added value....

Edit 1 to answer :
Looks like Chat GPT answer.
Why it is not me ordering the computer? I put photos of it to confirm my review after you flagged it to make it disapear.
What do you not understand when i say:
"I had to do much modifications in the BIOS so the computer can see the SSD (and I had to remove it to change the port of it, CSM, and so on...)."
Yes you explained how to do, but not a full information, and 10 days after the PC has been delivered. Why not just send the explanation with the PC?
You are selling a service, I order more than 4000€, just stop arguing and face the truth, your service is not that good.
And Mike, you are a joke, always trying to chatgpt all reviews. Level up

End of Edit 1

I have ordered 4000+€ parts to build a computer.
Good products (Full Rog strix / Lian Li / 4080 super...).
I have asked them to build the computer.
They charge Total amount: 173,74 EUR to build it.

When I receive the PC, I cannot use it, I cannot instal windows...
After I ask them (I have to wait 3 days because week end...) they tell me they have not tested the parts, they have switched on the computer with their own SSD... Because I didn't want to pay EUR 139.90 for WIndows 11 home and EUR 159.90 for Professional.

I had to do much modifications in the BIOS so the computer can see the SSD (and I had to remove it to change the port of it, CSM, and so on...).

This is , from my point of view, not acceptable when you buy 4200€ parts and ask them to assembly.
Not profesionnal.

Dear "olivier morel",

Update 2:

We've explained everything already and there is nothing to add regarding this toxic nonsense. Again, we are not installing anything for free if it's not being paid for, especially not without activation of the software.

Update:

Is it really necessary to defame a company employee as Chat GPT just because you didn't like or understand an answer?

"Why it is not me ordering the computer?"

→ It is not YOU = "olivier morel" who ordered that PC. The order was placed by another person including the invoice address so that person is our contractual partner, not you.

"Yes you explained how to do, but not a full information, and 10 days after the PC has been delivered. Why not just send the explanation with the PC?"

→ We would've done that ourselves if you had paid for it, which you didn't. We're not going to write lengthy manuals for free.

"You are selling a service, I order more than 4000€"

→ You only paid for the hardware and assembly. We already explained it. You ordered a system specifically without an operating system so we're not setting up anything. We also not going to offer free support if people don't know how to install an OS.

Original response:

You don't seem to be the person who ordered this system. In case of an RMA claim, please tell our contractual partner to contact us instead.

Thus far it seems unclear as to why exactly you are unable to install Windows. I must stress that the person who ordered the system decided not to order an operating system which is why we are not going to install it for you. The price for the assembly was only for the assembly of the hardware parts, not for installing or setting up software, hence the word "assembly". There is no basis for a partial refund that you asked for.

This obviously requires the person who orders a PC without software to know how to install an operating system and how to configure the BIOS for that. CSM should be disabled if you want to use above 4G decoding and Resizeable Bar, which will disable support for legacy devices. Also, the SSD you want to use for Windows needs to be formatted with the GUID Partition Table instead of MBR. In addition, you probably have to set the PCIe lanes of the PCIe slots of this particular motherboard to M.2 in order to see the NVMe drive in the BIOS. We already told you that in your support ticket and explained how to do that.

You are also repeatedly claiming that we didn't update the BIOS, which is untrue, because we did so. And yes, for such systems that are dispatched without an operating system we logically have to use a separate SSD with an OS to boot it from in order to run our benchmark and stability test suite, because how else could we do it?

Good till first faulty item

Good till first trouble. I spent over 5k in this shop, but I am out now. I sent faulty RAM (tested before on 3 different computers and when bar was inserted computer had random blue screen crashes - definitely faulty) back to them, and I got it back as full working!!! They are claiming some paragraph 437. So if you do not want warranty problems, avoid.

Edit:

Thanks for answer Mike

So to clarify. I bought matched memory pair. When both sticks were inserted (on default BIOS settings) computer crashed with totally random blue screen errors (once twice a day maybe). When only one stick - working one - was inserted, computer ran without any issues. But when just faulty stick was inserted crashing has somehow become even more intense. I ran memtest86+ from USB stick and no errors were found. Then I transferred faulty stick to other fully working computer with different components about 5 years old and - had same blue screen crashes again. So I was certain about fault before sending back with description of a problem. Now I am solving this issue with manufacturer.

Edit 2
Hello again, Mike

I am using logic here - if one stick of a matched pair is working and other not on a same slot on a same motherboard then is obviously faulty or mismatched to that level that causes problem which is still under warranty for matched pair. As said I tested on two different motherboards generations apart. These RAMs are on compatibility list for both motherboards. There are many such problems described on forums where memory tests do not recognize faulty ram.

Edit 3

So I am unfortunate that one part does not work in any of my motherboards, or maybe lucky that one does and I still can use half of kit. I will present this case to German and EU consumer protection service to get their opinion. I still think that when buying new part, working or not working can not be matter of luck.

Dear "Muto Lay",

Update 3:

If you buy a new RAM kit, you can easily test them and return them within the 14-day withdrawal period. And until 1 year after receipt of goods, the burden of proof for a fault at the moment of the passing of risk also lies with us. Your memory kit is, however, much older.

Update 2:

[Edit: Thank you for finally identifying yourself.]

You purchased the memory kit in question in November 2022 and apparently it worked since then. The burden of proof lies on you. We can even provide counter evidence that your memory kit still works perfectly today:
https://drive.google.com/drive/folders/1BL3qq3zCmuzb_XDeJ8U8QJZke0kqoOFU

The memory kit is CMK32GX4M2E3200C16 and it is *not* included in the QVL of any of the motherboards you purchased from us:

"I am using logic here - if one stick of a matched pair is working and other not on a same slot on a same motherboard then is obviously faulty or mismatched"

→ This is not logical. Of course some unsupported memory sticks sometimes work, some don't, no matter their kit combination. Silicon chips are not 100% identical to each other that's why there is a silicon lottery as well as silicon degradation. It depends on many factors, settings, timings, profiles, voltage, the correct slot usage and so on.

"There are many such problems described on forums where memory tests do not recognize faulty ram."

→ The vast majority of such forum posts obviously contains incorrect assumptions and solutions both. Memory that doesn't work stable with certain memory controllers in CPUs/motherboards or settings is not automatically faulty. That's simple logic. And yes, memory test tools are specifically designed to test memory regarding defects.

Update:

What you describe is unfortunately a totally normal occurrence and simply incompatibility with the respective memory controllers of each CPU. Those memory modules are not faulty. That's what is proven by various Memtest tools. Nowadays DDR4 and especially DDR5 RAM are commonly known to be very fickle and sticking to the official QVL of motherboards is becoming necessary. You also have to make sure to use the correct memory slots on the motherboard if you use two sticks. You can't just put them in anywhere. And again, the memory timings and clock settings in the BIOS must be correct. You can check the SPD values with CPU-Z. Your test method of merely testing a stick in a second system doesn't say much when it comes to RAM. You could test perfectly working memory modules on unsupported boards or with incorrect settings all day and they'd still not be faulty. The fact that only one stick worked is more evidence to that since the CPU's memory controller doesn't have as much to do with just one module. The supported clock rates with two modules are also always lower than with only one stick.

Original Response:

What is your customer or order number? Please contact me via email at "mike@caseking.de" or in our official support forums so that I can check your case. Supposedly defective memory modules can be easily verified as faulty with Memtest and similar tools. Your memory modules were apparently proven to be functional.

Many customers forget to activate the proper memory profiles like XMP or EXPO for their respective RAM modules in the BIOS which is often the actual cause for instability. Apart from that, overclocked memory is not compatible with every motherboard/chipset or memory controller/CPU.
