I have the Antec P180 and I really like it. It's very cool and very quiet.

If you're getting it, make sure that you get a PSU that's has the Voltage rails long enough. Most of the good PSU are sufficient (OCZ, Antec, CoolerMasters, etc.) are lengthy enough.

I also have the Gigabyte Aurora. It's another study and great case also. This case is the perfect setup for watercooling

G'luck and let us know how it turns out
