The Magnum SMA8, with its commanding presence, has proven to be the go-to case for professional system builders and case modders around the world. With its heavy-duty all aluminum construction and unsurpassed modularity, the SMA8 spans a diverse range of applications from forensic systems used by top government security agencies to all-out showcase builds featured in popular magazines.

 Enthusiast features include a slide-out motherboard tray that doubles as a tech station. Hinged, removable doors allow fast and easy access to the interior. In fact, the tool-less panel design allows the entire case to be stripped down to the frame in less than a minute. Cable management is a dream.

 The SMA8 includes CaseLabs’ innovative Flex-Bay system that allows users to tailor their case to their exact needs. Additional door panels, top covers, pedestals and related items allow for further customization. Finally, every individual part of the case is available separately, so modders can freely add their own distinctive touches and change them back in the future, if needed. From the hardware used to the powdercoat finish, every aspect of the case exudes quality that is second to none.

 When your build demands the very best, the Magnum SMA8 is a great choice.

The SMA8 was designed without a fixed I/O panel for the front. Instead, we created a 3.5'' bay mount directly under the switches. Now you have the freedom to have any type I/O panel you like or none at all! The switch assembly includes two switch plates, a solid version and one with a cut-out for your 3.5'' device.

We offer this 3.5'' device wih USB and HD audio. We can even color match it to your CaseLabs case!

    Just recived my magnum sma8 and best quality case. Its build like a tank. Recomended!

  2. Well worth the wait

    Posted by Unknown on 18th Apr 2016

    Can not say how much better this case is than any other case I have ever owned. There really is nothing that compares to it and it is more than worth the extra $ and wait.
    Customer service is top notch even after I kept harassing them with questions, changes, and updates.
    If you are scared of the wait time, I can not lie, the time goes by slow, but, once you receive the case you will be happy you waited.
    I'm pretty sure everyone has there case setup in their carts already. Just go ahead and click the checkout button!!!

  3. The best of the best!

    Posted by John T on 18th Mar 2016

    TLDR: 10/10 Will do business again. The Case Labs Team are all rock stars and are amazing at everything they do. You can not go wrong with one of these cases!

    At first I saw all the 5 star reviews and thought "psssh yeah right no company can be this perfect. I wonder if these reviews are fakes."

    I'll save few bucks and get a 900D instead. What a terrible decision that was. Had GPU clearance issues with an errant metal lip over the pcie brackets. What a load clearance issues in a case this size time to ship this back and get something that works.

    Before jumping in head first like the 900D I shot over a bunch of questions to the help line.
    It's so epic being able to ask a question no matter how technical and get a fast accurate reply back. Instead of the usual brush off or completely wrong answer.

    Feeling better after getting so much help I decided to bite the bullet.

    Friday night I get a big box and with a sticker "made in the USA." Don't see that everyday. That's cool. It's too late to get into a major project I'll save this for tomorrow morning. Sun rise, feels like Christmas morning. Rip open the box expecting to see a fully assembled case like a normal build.

    Instead what I see is so much better. Individually wrapped in heavy plastic separated by soft foam dividers bits and pieces of case greatness. Woah, now that is the most impressive shipping I've ever seen period. These guys at Case Labs must be proud of what they make.

    *One easy SMA-8 and Pedestal assembly later*

    Over the course of assembly I saved every piece of tape. I wound up with a ball of tape large enough to choke a grizzly bear.
    Seriously Case Labs deserve to be proud of their product for going the extra mile to protect it like that. Now THIS is a enthusiast PC case! Spent 2 hours drooling over the gorgeous finish on this case. Then I found the first problem and the only problem.

    A slightly warped double 5.25 ventilated flex bay cover dun Dun DUN!!!
    Shoot a quick email and picture to KC (Staff member I was asking questions to) saying I had a warped cover and what I needed to do to get it fixed or order a couple of single flex bay covers. Get a reply back, he was more worried about the cover than I was.
    "I will have a replacement cover shipped out to you."

    *3 days later*

    Holy crap dude! Is this my cover?! That was blazing fast. I didn't even have to do anything. Swap out the covers and the case is absolutely flawless. I've never felt proud to own any kind of computer component. Until Today.

    Such an amazing case. Such a joy to put together. Such a joy to assemble a system in. Case Labs, your products are amazing. Your support for those products is legendary. Worth every last penny. If I had a trophy pedestal that is where I'd put this case. Keep up the outstanding work!

  4. You get what you pay for!

    Posted by Aaron on 14th Mar 2016

    To those of you looking at these cases and comparing price tags to other brands such as the Corsair 900D or anything else let me just say that you get what you pay for with Caselabs. My SMA8 screams high quality with every aspect from the case itself all down to the packaging. To those who are skeptical about the price tag, buy from Caselabs, you will not regret it.

  5. Perfection

    Posted by John on 13th Feb 2016

    One of the panels was warped and I had to bend it back to straighten it out. Easy fix, but I'm blaming the shipper for that one. Other than that, its as advertised. Best case ever made imo.

  6. Fantastic

    Posted by Josh on 8th Feb 2016

    Best PC case I ever had Top Quality Materials and build I only wish I discovered case labs sooner
    Most definitely worth the price tag

  7. Exactly what I wanted.

    Posted by Stephen on 31st Jan 2016

    The SMA8 will be my 5th or 6th custom build. This case is absolutely perfect. All parts measured exactly right, all holes perfect, all hardware highest quality I've ever seen. If you are serious at all about a custom build, this is the best available, without qualification. I spent about 2-3 days slowly putting the case together but it could have been done in an afternoon. Mine has the gunmetal finish which is super awesome as well. 10 stars to Caselabs for a fantastic product. I'll be back for my next build.

  8. Best Case Ever

    Posted by Matt on 9th Jan 2016

    So I ordered my SMA8 on 30 NOV 2015 and got it right around Christmas time as expected. Lets start by the packing. Fantastic packaging everything was individually raped in plastic and then a layer of Styrofoam. Nothing was damaged or had any scratches. Assembling the case was pretty straight forward but the directions could have been a little more in depth. I only have one thing to complain about and that is I wish they would send a case cover so when I'm done using my computer I can cover it up so is doesn't get so dusty. Over all CaseLabs Great job I have defiantly recommended your protects and showed all my friends what you can do with no compromises. Great work.

  9. Best Case ever HAD

    Posted by Andre Cavaco on 2nd Jan 2016

    Its the best built case i ever had, arrived very well packed , and with a lot of extra screws and pieces that u might need , very good instructions on how to assemble it , worth every dolar/euro , there is no other case like it on the market

  10. The Ultimate PC Builders/Modders/Gamers/Everything Case haha :D Seriously tho, best case money can buy.

    Posted by Josh S. on 5th Nov 2015

    The quality is insane on these cases. Absolutely worth the money and wait time if you can afford it. If you enjoy building PC's you have to have one of these cases, so customizable and easy to work with. I'm in big trouble now because ever time I want to build a new PC I going to have to fork out for one of these bad boys lol. Also the customer service is great, KC put up with me bothering him for about a month about gun metal grey cases haha thanks KC. All I can say is do it, support this company, we need more like them.
