  1. Spacious!

    Posted by Charles Ball on 19th Aug 2016

    Excellent case, lots of room to work in

  2. End-game

    Posted by Jordan C on 10th Jul 2016

    I wouldn't be posting this if I weren't a PC hardware enthusiast., given the location of this review.

    So, I'll start this off in a different way. I like headphones. I spent years buying different models and comparing them, all underneath the price tag of $150 or so. Until I saved up and finally said, "Hey, this ends now. I'm dropping $600 on the HD 650 with a good DAC and amp and I'm done." That was it. Three years later and I have no impulse for any other headphone setup. Endgame achieved.

    Meanwhile, for even longer, I've been a case junkie. In the past 3 years I've used 4 cases for my desktop. I've built entirely new mITX systems just because I was excited about a new case and to see what I could do with it.

    All of these things brought slight changes in functionality, along with the driving force of some new paintjob or plastic shell for aesthetics... Friends telling me I'm nuts for having such a passion for cases. I mean, really. Computex for me has always been primarily for new case news.

    But, then I finally did it. After flirting with the customization options of the Mercury series for close to two years, I finally did it again... and clicked order. And that's it. Now I know I have my endgame chassis. The quality is impeccable. This is a tank, and once you have your system built and running, you will (I guarantee) constantly find yourself knocking on it and then running your hand across it for the first week that you have it.

  3. Flawless Case

    Posted by Gadiel Santiago on 4th Jul 2016

    This is in my opinion the best case to put a EATX motherboard horizontally so the pci slots don't get damaged when a graphics card pulls them in the vertical position. It has tons of options for any idea you can have, the only thing I wished it come with was a acrylic where the expansion bays are but it's ok I will create a custom one. Like all cases from caselabs you have tons of options and can customize it to your needs or the customer needs if you are building for someone. It can get expensive but you get what you pay for, a top of the line product that can't be found anywhere else and best of all made in US!

  4. Definitely the best case I've purchased

    Posted by nuojin li on 5th Jun 2016

    Easily assemble, full customized, and even the small parts they do well for u ( I mean the clearly marks for screws in different pockets.) Also, Since more guys did write the reviews for it, I won't do it as much.
    Just give a hint: look carefully and feel free to ask questions when customize the case, then after a couple weeks best case is ur.

  5. Rock Solid Case

    Posted by John Bartish on 20th May 2016

    Both case assembly and component installations were extremely easy to do. I was surprised at how thick the aluminum was. Other brands are flimsy by comparison. Excellent paint job too. I thought I accidently scratched the case during assembly but as it turns out my concern was unfounded.

    I like the separate motherboard tray because it allowed me to install the cpu, heatsink, memory and assorted motherboard cables with the tray outside the case. In addition, with the motherboard tray removed it is very easy to install other components such as case fans, fan controller, and an I/O panel.

    There was only one very minor issue. The case does not come with a power supply mounting bracket. When the psu is attached to the rear panel the bottom of the psu does not rest on the bottom case panel. There is a bit of open space between the psu and the bottom case panel. Although the thick aluminum panels are strong enough to support a psu I decided to purchase a psu mounting bracket from the CaseLabs store.

    Overall the Mercury S8 is an excellent case. I purchased my first pc in December 1984 and have been upgrading, building, and case modding ever since. I can honestly say this is the last case I will ever buy.

  6. Best Case I ever bought !

    Posted by Rober H. on 4th May 2016

    Hands-down one of the finest computer cases ever built . Took a little longer to receive but well worth the wait could not be happier . The paint job was flawless everything arrived as described . Assembly was very easy and very strong construction great job . Highly recommend it to anyone who wants a serious high-grade case .

  7. Flawless!

    Posted by MartyG on 1st May 2016

    As advised by CaseLabs (KC), my Mercury S8 arrived slightly beyond the advertised delivery time frame in an extra heavy duty cardboard box. Each sub assembly was wrapped in a heavy duty plastic bag. I checked each piece like it was a newborn. The "Gunmetal" finish on each was perfection and the assembly process revealed the fit was as good as the finish.
    If you're looking for the best custom, USA made case for your next build look no further than CaseLabs.

  8. Sorry but Pleased

    Posted by Patrick Lawson on 5th Feb 2016

    I am, in way sorry that it is done but I am pleased with the result. If I could think of half of an excuse I would buy another Caselabs case just to do it again. My case is the one in the gallery under DominoBlu if you want to see some scruffy photos.
    I cannot really add a whole lot to what others have said before me so I will keep this brief. The quality of the product is excellent. A lot of thinking has gone into its design. My problem was I was spoiled by choice when I say how many different approaches I could take to install my two separate loops. Customer service was also exemplary. En route to Scotland the shipping company managed to damage a couple of the major parts of my S8 and Pedestal. They were replaced ASAP without quibble. I can heartily recommend this company and their products.

  9. Excellent Case

    Posted by Scott Harwell on 27th Dec 2015

    This is my first CaseLabs case and I have been very impressed with both the quality of the product and the CaseLabs customer service. One of the parts arrived broken during delivery; KC ordered a replacement shipped that day. The case itself is incredibly roomy with plenty of space for even the largest water cooling builds. I am very impressed with the rigidity of the frame. Even a full speed, my DDC pump doesn't vibrate the chassis at all. You absolutely get what you pay for with a CaseLabs case!

  10. My first Case Labs case

    Posted by Unknown on 16th Nov 2015

    This has been 100% positive. I have been looking for a case upgrade for a while and this case has done it for me. The S8 is very spacy yet doesn't take up too much room vertically even with the pedestal. I love the ability to customize the slots in every caselab cases. This is now my goto place my cases.

    The only thought I have is the ability to customize a bit more color.
