Product Description


Fixed Case Options:

Bottom Chassis Section: Solid

Lower Chamber Covers: Ventilated

Power and Reset Switches: Standard with sleeved cables

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!

  1. HUGE

    Posted by M F ALI on 19th Sep 2016

    Oh my lord. This case is huge. I mean its giant, my 3 year old can almost sit in it. The quality has left me speechless. It is flawless. The workmanship is without equal. Flatpacks can be daunting but this is nothing like Ikea. Everything is easy to assemble and I didn't struggle with a single piece. It fit together like a piece of Art, which it really is.

  2. Precision

    Posted by James Whitney on 1st Sep 2016

    I am truly amazed at how precise the assembly is! I've assembled many flat pack items before and I was in awe at how well the case fit together.

    It really is a marvel of engineering. Well done guys!

  3. The ultimate

    Posted by Gary on 16th Aug 2016

    Excellent build quality . White is stunning . With optional 40mm top you can fit any Rad. Endless expansion . Can fit 3 rads. This is the case to get!!!!!
    Will last you a lifetime

    Expensive . Takes 6 weeks to get to you .

  4. Best Case I've Ever Had

    Posted by Paul Trampert on 17th Jul 2016

    This case is *fantastic*. Recently did my first watercooling build in this case and it was an absolute dream to work with. That said, here's some of things to be aware of:

    * This is a very large case - I would highly recommend the heavy-duty casters
    * If you get the front panel audio/usb and your mobo has the front panel audio header in the back, get an extension cable.
    * The 3x120mm fan mount lines up with the basement separator, not the 3x140mm.
    * A radiator + fans at the top of the case will mostly block the cable management holes on top of the mobo tray.

    These aren't bad things by any stretch - just be aware of them when planning your build.

  5. Best case, bar none.

    Posted by Jason C. on 28th May 2016

    Ultimate quality and it is so durable. Also, it was packed and shipped like it was a newborn. The attention to detail from Caselabs is unreal. I love that the limitation to configuration is my creativity. I only regret that the 240mm extension for the top is no longer an option (for more read configs), but it doesn't take anything away from how much I love this case!

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

  7. 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!!!

  8. 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!

  9. 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.

  10. 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.
