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. BFC (Big $#@% Case)

    Posted by Jason on 8th Nov 2016

    I use this case to house both a water cooling solution and disk arrays. It does both quite nicely at the same time with plenty of room between video cards and hot swap cages to put a large reservoir. The case itself is rather light and sturdy, leaving headroom to stick a bunch of crap inside and still have it a lift-able case so I can put it on the table and work on it. (Then again any case this size that you really do plan on filling with stuff, you need to be mindful of the total weight and what you can do to safely lift that much weight.)

    The design of this case is really nice. It is real easy to route cables and thick water tubes behind the m/b tray, making for a nice clean layout. Every case part you get from CaseLabs is top notch and you can always bug them and get a reasonably prompt response if there is a problem. I did need to get extensions for the CPU power connectors, but consider if you putting out the money for this case, you will probably buy extensions anyway for styling reasons. If you were to go with any competitor case you would just go crazy / grimace when you have to work on the case or think about showing somebody, but with this case it is easy to put together a thing of beauty and function at the same time. I still drilled some holes for my custom water cooling setup, but this was rather easy and really more personal preference for the look I was trying to achieve. When I evaluated what drilling mods I needed to make for various cases, I came up with the CaseLabs case is hands down the easiest case to mod as it is both already closest to what I was looking for and you can add / remove whatever part of the case you need in order to have the best access possible to the part(s) you are going to mod. Basically any other case things are either riveted together or at least there is some funky layout quirk that will make the desired end result a lot harder to achieve than what you get with this case.

    When thinking about what you need for a high end gaming rig today, I would venture to say this is probably the most case you could make use of. A 560mm long 86mm thick rad fits just fine in the bottom chamber with eight 140mm x 25mm push-pull fans. That is plenty to cool two Titan X Pascal cards and do whatever overclocking you can squeeze out of the cards. You cannot really make use of much more due to driver limitations. Then there are various places you can stick extra rads to cool motherboard and CPU components and have plenty of radiator to overclock the heck out of your CPU and still run fans and everything at whisper quiet speeds. Just be mindful if you are going to stick a rad on top, use the taller 39mm top panel so you can fit a reasonably thick rad and push-pull fans. I would definitely get the casters as water cooling parts, especially a 560mm rad and full cover water blocks can get to be heavy. Also this is pretty much the biggest case in all dimensions I can fit into the space I have for it; it is almost too big. I would definitely check the dimensions you have available to stick this case in because it is a lot bigger than a full tower case.

  2. Perfect

    Posted by Aaron on 12th Oct 2016

    This case is designed perfectly and the quality is amazing. The powder coat looks awesome too. I literally can't say anything bad about it. I love this case and it really makes my build look great.

  3. 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.

  4. 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!

  5. 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 .

  6. 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.

  7. 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!


    Posted by Peter Schmidt on 28th May 2016

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

  9. 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!!!

  10. 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!
