  1. Exceptional quality and simple, yet stylish looks

    Posted by Ilia Draznin on 30th Mar 2015

    This is the last case you'll ever need to buy. I received the case "flat" (i.e. not assembled) and the packaging was excellent - you don't need to worry about any damage during shipping. The assembly instructions were clear and easy to follow and I enjoyed the entire process. The quality of all the pieces was excellent throughout - not a scratch, or a sharp edge, or a missed spot in sight.

    The finished case looks great (if you want the minimalist look), feels extremely sturdy and has plenty of room inside for almost any water cooling setup you could imagine. There are plenty of grommet holes for cable routing, the flex-bay system is very convenient as it makes it extremely easy to rearrange your drives, front intake fans, front rad, or fan controller. I also particularly love the extra space at the back (behind the motherboard) - cable management is a breeze.

    Finally, I do have one nitpick with CaseLabs - fan filters. Yes, I know they already technically addressed the issue, but I'll keep harping about it. I think they should reconsider adding fan filters as an add-on component. Fact is, it's very hard to find something that would work well, and look well, with the cases. The DEMCi filters are okay, but they're not perfect. If they were to do something themselves - something with the same high quality, and the look that matches the cases - that stuff would fly off the shelves.

  2. Literally faultless

    Posted by Dan on 16th Mar 2015

    The quality and design are without question faultless.

    Theyve clearly thought about every single detail when designing this case and it really shows. just little things like how theve designed i/o so the cables enter cable management and never encroach inside the case.

    I ordered this flat packed and everything was just so organised out of the box; beautifully labeled individual separate sealed bags in for me in order to build it myself.

    Also, adding spare parts, but not just screws, spare closing mechanisms, its just really evident throughout that theyve spent the time to think of everything in order to deliver a great product.

    Communication throughout my customized order process with these guys has been spot on. Im an international buyer and things could not have gone smoother.

  3. There is nothing like it

    Posted by Xerxes on 2nd Mar 2015

    I have had many cases in my twenty + years in IT and I have never seen anything like this type of case for a home PC. It's the best I have ever had!

  4. Very nice case

    Posted by Eric schmidt on 9th Feb 2015

    look's great. Hard to beleave this case is this big. This is my first new case in 16 years I'm usually more worried about actual mother boards, CPU and video than cases until lately with the bigger heat sinks and more heat from modern computers these days. So if you want superior quality and a water cooling friendly case, then just buy one of these.

  5. NICE!

  6. 5 5 Stars Are Not Enough

    Posted by Roger Moore on 29th Dec 2014

    Design and quality are the finest of any case that I have seen. The Lexus of cases....and there is a large gap in quality between this case and all the rest.

  7. Would give more stars if I could

    Posted by sociopath on 14th Dec 2014

    I read many reviews, looked through build threads and watched many videos before deciding to buy this case. The build quality is insane, options almost endless, expandability unrivaled and in my opinion a beautiful package.
    If you want a top quality case, like the style and have the money to spend. Stop thinking about it and just buy the thing. It's not possible to go wrong with anything that has a Caselabs logo on it.
    I don't have the room or the funds, but I already want another case just so I can build another PC that I don't need. Now that I think about it, I almost have enough parts to build another system....

  8. the best

    Posted by Unknown on 12th Dec 2014

    No one makes a better case. Seriously. No one.

  9. It will put a smile from ear to ear on your face!

    Posted by Nicholas Hansen on 1st Jul 2014

    I really can't fully explain my feelings about my SM8, at least without sounding like an overly enthusiastic little kid!! Just like the title, it literally put a huge grin on my face the moment I opened the box and still does even weeks later after ive finished my build. The quality, style, modularity and customization, accessibility and provisions are of the absolute utmost appraisal. Just the feel of the powder coat finish, the superb two tone paintjob provided exactly how i asked, and the weight in perfect balance from all aluminum construction make the case boast convenience combined with durability perfected. it truly is one of a kind. You purchase this, and you will never need another case again, GAURANTEED!

    For my planned build, the complexity of my cooling system was very high, and throughout the process my plans were constantly changed and many unexpected problems arose. With a normal case, this would have created delay after delay, and constant frustration... But due to the insane level of customization and features of Caselabs, I was able to just "go with the flow!" Power supply in the way? no problem. Had a coolant leak? no problem. Not enough cable or storage space? no problem!! its awesome!!

    Id also like to mention their customer support was also outstanding as well. KC swiftly and speedily answered and even encouraged every question I had as they truly desired my full satisfaction.

    Seriously, if you are even remotely considering ANY Caselabs case, BUY IT! You will not regret it.

  10. Excellent case !

    Posted by Unknown on 8th Jun 2014

    This is the best case I have ever owned (and the first Case Labs one !, I owned up to now mostly Cooler Master and Lian Li cases...). Manufacturing is incredibly precise and mouting the case is flawless, (shipped flat-packed, I mounted the SM8 in maybe 1 hour, assembly guide is very clear with many pictures of each part). Doors could be a bit easier to open (on my mount, you need two hands to open a door). Apart from that (but you don't open your case doors very day), everything else is perfect. Space and cooling is incredible and even more since you install flex bays and device mounts only where you need them... Case is of course very modular and offers many configuration options, especially for fan and radiator placement. Finally, support is very professional.
