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. 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!

  2. 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.

    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.

  5. Splendid!

    Posted by Christophe on 16th May 2014

    This case is huge compared to everything I have ever owned, but I wanted the space for radiators and there are plenty!
    I've been in contact with Caselabs before I placed my order to know the clearance I would have with the radiators I wanted to put in, received fast and precise answer. They know their job!
    The build quality is just perfect.
