Awesome case – A amazing case to build in, way to get to plenty of air flow and tons of space

Great case – Good looking case used to do an r2d2 Star Wars build

IN LOVE – This is for my husbands gaming setup. It fits on a IKEA square shelf on the top, it’s too small to fit inside but it looks great on display sitting on the top. Our old ones were also on the top but they hung over and didn’t look as aesthetically pleasing!

Matcha Green!!! – This was a birthday gift to myself for my gaming setup! I love the color and Thermaltake has fans and a liquid air color that match the Matcha green! It’s girly without being too girly and I love it with all the matching pieces! It also fits perfectly on our setup and the cords go down the back so you don’t have to see them like with our old computers!

Awesome micro-atx case! – Had fun building in it. Squeezed in an 7900xt GPU without a problem. Great airflow and access. Highly recommend if you are looking for a case that a different form factor.

Functional Eye Candy – Building in this case wasn’t easy (then again it’s rarely easy for myself since I’ve only built PCs twice), but it’s well worth it. Very attractive looking case, and I love how easily you can take panels off without the need for screws. It does require some planning on which cables will be fed into the interior into the graphics card and\or motherboard since the I\O comes out of the top of the case instead of the bottom, so be aware.

Thermaltake is great. – Great case! Excellent airflow and fairly easy to work in.

Tower 300 worth the money – The case was easy to work with and has a lot of space and can support most ATX power supplies. Not to mention gpu and AIO cooling space for 3 fan systems

Really cool design – I love the design look great just a little too tall for my desk

Beautiful small form factor case! – Such a good looking case but if you have a beefy build the heat will not be nice to your pc components. I ran a 4090 with a Asus Ryujin 3 240mm and the heat was too much for the case to exhaust. If your build is less beefy then I’d definitely recommend this case.

Worth every penny – I love thermal take cases. I had my last one for 10 years and it survived 3 moves. But this case just looks great and has great airflow. It was very easy to figure out and hides all the cables great. I didn’t even build a new pc I just moved every thing into this case and it feels like a brand new pc. 10 out of 10 would recommend.

I love the Tower series! – Love these cases in The Tower series, I actually upgraded my Tower 100 to this case, this particular color reminds me of Halo, I call it my Master Chief PC!
EEPW (verified owner) –
I love it! – I love this case! It is easy to open and easy to work with adding all of your preferred parts. It’s also easy to clean and customize.the color is perfect as well!

Fantastic case – Great case that’s well designed and very easy to work with. Takes a few minutes to disassemble and has lots of room for upgrades alor changes. Only thing to note is access to motherboard IO was not obvious at first as connections are inside case. but there is plenty of over head for cables antenna or dongles
CrystalBall3r (verified owner) –
Fantastic case! – Love the build quality and part size compatibility within a reasonable footprint. I was also pleasantly surprised by how well laid out the case is inside and how much of a joy to build in it was.
Verified Buyer (verified owner) –
Tight but beautiful – Got this for the kid’s setup. Had some old parts to throw together so I got them this case, then I decided to ramp it up with a bunch of rbg (usually don’t do the rbg because I just use my rig for mostly work).
Pros: looks great when everything is done.
Cons: hard to run wiring through especially if you have a big GPU. The ports for the motherboard and the GPU are hard to access and really make that top part a tight fit. If you have big hands, this case may not be for you.

Beautiful Case – The Thermaltake tower series is one that has intrigued me for a long time. The design is bizarre and mounting a motherboard at a 90 degree angle is very odd. Overall its a great case. Great Build Quaility, Looks Great, Easy to Work in. My one knit is that you have to route all the cables plugged into your motherboard through the top and there is only one cutout to run them through so things get pretty jammed. Overall though I’d say its a great case and I would build in it again.

Very solid – Prefect for smaller spaces, while still being optimal for gaming etc.
