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

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.

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.

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.
