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.

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.

This case is old, and I have a lot of complaints about it. The top of the case has light shining through in some spots, but I'm working on patching them up with electrical tape. The inside of the case is not painted, I had to custom paint mine. The top has an un-removable 240mm fan in the top, which complicated spray painting. The cable management is ****, as you can see in my build. I can't find a way to screw the front panels on securely in the absence of the hard drive trays, which I've removed. With a Hyper 212 EVO, the inside-of-window fan holder is rendered useless, and has since been removed. The stock fans that come with the case are extremely loud with the switch turned to high.

It's Cool. It's Blue. It has almost no cable management, and the LED's can't be turned off. And the LED's are really, really bright. Aside from that fact, it's solid steel and has 3 120mm fans which have 3 speed controllers, and one 200mm on top that also has three speeds but no LED's interestingly enough.

I love the way this case looks, and how much airflow it gets; but its age is catching up with it. Has almost no cable management, save for the newer models that have a few holes to the right of the motherboard tray. Again, due to its age, there are no dust filters that come included. the 200mm fan on the top is nice though.
