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. No Going Back!

    Posted by Unknown on 1st Dec 2014

    The build quality, customer service, and experience of assembling this case are the best I have ever experienced in a product. You can immediately tell that the build quality and craftsmanship of CaseLabs cases are top notch when you first open the box and begin assembling the case. After experiencing a CaseLabs case I can not fathom going back to another mass produced consumer case again. The experience from the time I customized my order, to the moment the case was fully assembled is like no other. If you are in the market for a new case and want a superior product, look no further!

  2. Not for everyone, but delivers what it should

    Posted by GhostHitWall on 24th Nov 2014

    Customer Support was really good.
    Build quality+shipping meets its price.

    Spare parts come in handy especially when you are modding your case.

    Install menu is not smart, but no one would have problem I assume.

    Before you buy, make sure you are willing to drill mounting wholes/pass through. And apparently watercooling .

  3. Awesome

    Posted by Unknown on 15th Nov 2014

    Best case I have ever owned by far. So much space makes water cooling easy.

  4. The last case I will ever have to buy

    Posted by Mickey Dair on 29th Sep 2014

    The best case I have ever purchased and I'm pretty sure the last PC case I will ever need to purchase.

    There is enough room to make anyone happy wither you air cool or water cool. This is a case that you never have to worry about the length of any video card you buy. You never have to worry about space for anything ever again.

    I knew there was a lot of room for cable management, but after I put the case together it is a lot more than what it looked like in the pictures and video reviews I have seen.

    Hard drive mounts are very cool mounted in the cable management area, so there are no hard drive cages getting in the way of case air flow. Hard drive cages can always make any case look cluttered and ruin it's aesthetics. That will not happen with the SMA8.

    The white paint job I chose is excellent and very clean.

    Every time I have built a new PC I have to buy a new case because the new components don't work in the older case or the build quality does not stand the test of time.

    That will not be the way it is with this case. Because of it's simple beauty and the sheer amount of space this case is very future proof.

    It is somewhat modular so in theory if there is a radical change in, let's say mother board design all CaseLabs needs to do is design a new mother board tray and you can slide it into the existing case.

    You have to put it together, and I thought it was going to be intimidating, but it was really easy. CaseLabs gives you all the tools you need and plenty of screws to spare. Everything was well packaged and labeled. You can tell a lot of care and attention to detail went into the not just the case but the packaging.

    Yes this case is expensive, but it will be the last case I will ever buy and over time it will pay for itself.

  5. Best Case Ever

    Posted by Greattar on 22nd Sep 2014

    I bought this wonderful case from KC Shop on the internet and i am very happy and pleased to have such a great product.It has everything that you need from a case!If you ask me, this is the best case in the whole world.It is very easy to build the system inside and everything that you put just fits together perfectly.
    From the beginning since i placed my order, KC helped me a lot with everything including the shipping, and the best thing is that i din't have to wait too long for this case,'cause i received it in a few days.
    I'll definitely buy again from CaseLabs.

  6. The Last Case you'll Ever Need (Though you'll want another)

    Posted by Tyler Perry on 21st Sep 2014

    This might be the last case I'll ever NEED to buy. Of course with how much I love this case I'll probably buy another CaseLabs, but needless to say this will last a lifetime.

    I ordered this case to replace my Lianli V2000 that I'd owned for 12 years. I was reluctant to order something new, as I held the V2000 as the standard for build quality and didn't want to compromise.

    The Magnum SMA8 Blows my V2000 out of the water. The V2000 is comparable to an aluminum can in quality to the SMA8's aluminum which feels as sturdy as a bike frame. The build quality of the V2000 is basically a cheap pressed aluminum Taiwanese case in comparison to the American made CaseLabs. The Magnum SMA8 is a tank, and now holds the gold/platinum standard for high quality cases in my eyes.
    The strength of the aluminum used in the SMA8 is the same quality you would find in fabrication and construction. It's high quality aluminum alloy (5052 H32, similar quality to some of the medium-end all aluminum bicycle frames, though 60xx is more commonly used on bikes). The design incorporates everything you could want. It is obvious the designers put a lot of thought behind this case, with ease of access and ability to incorporate any modification you want to it. This case is a piece of art.

  7. Best case I have ever build in

    Posted by Henrik Dige Semark on 6th Sep 2014

    This CaseLabs case is definitely one of the best cases I have ever build in! Everything just fits together, and the build quality is exceptional. You get a feeling right away, that things a made out of good materials that are meant to last for many years - the only problem I had was a side-door panel with a big scratch in the corner, which looks like a production slip-up... but nothing that takes away the feeling of quality.

    A huge thing for me personally is the customer service really. Before my order I wrote them to hear about something, and I didn't wait for long before an answer arrived. After my order was placed I discovered an error that I made, so I wrote a reply to my first email and asked what to do, and without any problems things were corrected - so without any hesitation I can comfortably say there service is second to none.

    The shipping was an absolute delight to open, everything is wrapped securely into it's own plastic bag, and separated by thick cardboard - I was able to bring it back home to Denmark myself after a trip to the US, but I would have no problem in saying that nothing would had happen with the content, even if it was send all the way.

    This was my first CaseLabs, but it'll not be the last, I can guarantee that!

  8. Top Notch Quality Case and Service

    Posted by Richard Dowling on 30th Jun 2014

    CaseLabs make exceptional cases. If you want a case that will last for many years and multiple builds look no further! It comes in a large box in parts. Which some would look down on, however I loved building the case. You really get to appreciate the quality and attention to detail.

    As for shipping, I live in northern Canada and many things shipped to me never survive the ride. CaseLabs packaged the case parts amazingly!! There was absolutely no issues there.

    Also a huge thing for me personally is customer service. Which after emailing and chatting with them on the phone I can say there service is second to none.

  10. Exceptional

    Posted by Piotr Miszczak on 1st Jun 2014

    This case is best all-rounder I've come across in my life. Excellent customer support. Would be nice to see some recomedations what to buy during configuration of the case, but it's revelant only to new to Case Labs customers.
