The STH10 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. sorry, 4.9.

    Posted by Ross on 4th Aug 2017

    Beautiful case , pure artwork !

    I will not give you a 5/5 because the instructions are not great.Good thing I'm a fabricator.

    Nice thick metal, I like all the studs and welded-t-bolts.
    I can't wait to get to building this machine , sweetest case ever !
    I hope I can do it justice.

  2. Best case ever

    Posted by kenneth way on 10th Jul 2016

    I received my case in February in gunmetal,when I received the box opened it up and took out all the pieces and there are alot of them they were in perfect condition. It didn't take to long to put together and everything went together tightly. If your are modding this case it is pretty thick. All in all I am very pleased with this case and wish I would have bought it sooner I give it 10 out of 10. If the price is making you think twice dont.

  3. The must have case for enthusiasts!

    Posted by Unknown on 25th Mar 2016

    Coming from a Coolermaster haf x 932 I instantly fell love with this case the room it has is just amazing.The instructions were easy to understand and the packing was well done for safe transit, and the case is build to last. I like that caselabs gave enough screws to get the job done and for future projects. If your pc has a custom water cooling setup then this is the case for you.

  4. Pretty much the best case you can buy.

    Posted by Mesa on 30th Nov 2015

    I knew that this case was going to be amazing, but you don't really understand how awesome this thing is until you take it out of the box. Every care is taken to ensure it ships safely and the quality of the material is like nothing else. You will be able to fit absolutely anything you want in this case and cable management is the easiest I have ever seen, you have a solid 2.5-3 inches of space in between the case wall and the motherboard tray to manage your cables (and anything else you could possibly want to put in there). On top of everything else the case just looks professional, it just looks like an industrial machine, there are no unnecessary external frills, or any of the cringy "G4MER" features like obnoxious LEDs. The only thing I would recommend is that CaseLabs ship these with a set of rubber O-rings to put on all of the panel clips and knobs, as the case can make an annoying rattling noise if one of them comes loose.

  5. THE GIANT !!!

    Highly recommended if you want to using it as a Water Cooling ! JUST

    Excellent build quality.

  6. Happy STH10 owner

    Posted by PvL on 8th Sep 2015

    After 2 years of watching pictures, drewling over youtube videos and saving every penny, I now have my STH10.
    All reviews on here say the same, so no need to tell you that this case is (one of) the best one on the market.
    It's like having a Italian Sportscar, I now have a Caselabs case, no need to elaborate more.
    But a few words:
    Case: Phenominal (build and freedom)
    Caselabs team: Customer service is outstanding
    Fair enough, you have to wait a few weeks for the case to arrive, but this is the safe with bespoke furniture, cars etc
    10 stars if I could :)

  7. Effortless Water Cooling

    Posted by Chris D on 15th Aug 2015

    You get what you pay for and this is no exception. While CaseLabs is certainly expensive compared to other (uncomparable) options the quality and ease just can not be argued.

    My main reason for upgrading to such a premium case was I was tired of the maintenance struggles with my custom water cooling loop. Even if the other cases had the room I wanted there were very limited options for making flushing or cleaning the loop less of a chore.

    Upon separating the parts the first thing I noticed is how much of a difference the aluminium construction makes. There are certain pieces I started tapping because they felt s light I had to question whether they were metal or not. This means that despite the size of the case it is really light on its own. Even after I fully built the machine with 3 480 radiators and a 240 Radiator the biggest challenge for me to lift it alone was the size and not the weight itself. In fact I am fairly certain it is lighter than my last Full Tower Case despite being 25-50% larger.

    The bottom compartment became quite cluttered between a 480 and 240 Rad, a pump and a PSU but even then it was not overly difficult to fit all of the components, the tubing, wiring and draining system without too much effort.

    The top compartment by comparison is barren with perfect airflow between two 480 Radiators.

    The only thing that I can say which really shocked me was just how big the case is. I knew the case was big when I ordered it but the pictures and the specs sheet just do not give due credit to the massiveness of this case. If you are looking to buy this case build a cardboard box with the sepcs sheet to get a true visual representation of what you are buying.

    That is by no means a complaint! If it wasn't for the massive size I would not have been able to do everything I wanted and more as effortlessly as I did it. This is more a warning to make sure you know what you are getting in to because the case is larger than the TV's in many family households and obviously several times as thick.

    If you plan on watercooling and want as much in case real estate as possible this is a perfect case. And I do mean perfect. If the size is a little too much then I would happily recommend the Magnum SMA8 instead as it is this case, more or less, without the upper compartment which is a substantial part of the size.

    If you have the budget and are an enthusiast then in my opinion it is worth every penny to invest in a CaseLabs case.

  8. overall great product

    Posted by mike hoang on 27th Apr 2015

    This case was definitely well made. Everything was nicely packaged and I would definitely buy from caselabs again. I am giving it a 4 out of 5 because the instructions could be better and more detailed. Also if you buy a 700 dollar case wheels shouldn't be separated, but included. Same with some other accessories like dust filters. I had to purchase mine somewhere else. Overall I am a very happy customer and caselab knows what they are doing.

  9. Only Just the beginning

    Posted by Unknown on 23rd Mar 2015

    I have recieved and built my magnum STH10, and nothing could have been better! Though I am not able to speculate on the full potential yet without having most of the hardware going inside as of yet... There remains so much potential and possibility with all of that space in such a well built case. If I ever build another pc it will rest inside another CaseLabs computer case without a doubt.

  10. Brilliant Case

    Posted by Unknown on 5th Feb 2015

    Its just the best case i have ever bought.

    It Looks amazing and neet. It is big and has a ton of diffrent Options. Best case for wathercooling.
