from completed build My First Gaming PC

Case is awesome, room for cable management is not so.

from completed build Burning Chrome

I've had this case for over 6 years and it still fits the bill. It is not tooless. There is not really a place to fit 2.5" drives. Hidden cable routing opportunities are next to non-existent, but with a modular power supply and some inginuity, IT CAN BE DONE! I also give this high rating because it has a decent style without being too absurd.

from completed build Blue

Older case, famous for its poor cable management and not toolless. Swapping the front cages around can be a pain. SSD mounting point seems weirdly positioned. Lacks an included filter. But it's solidly built, includes four fans, has spectacular airflow and easily-removable side panels, holds all my components, and looks good doing it.

from completed build Powered by Kryptonite

This case has served me well over the years but now gives me issues. The window side panel no longer wants to sit properly. The front pieces do not sit flush. The hard drive cages are a ***** to remove. The stock fans are absolute trash. After I broke the fan clips on the clear plastic under the mesh, I took it out and now I can see more clearly into my case and more air can move through it.
