I use this case with an Antec NeoPower 480 PS, and it's simply wonderful. U can mount the HD's so the cables are completely hidden, which makes for a tidy look. I removed the front 120mm fan and cut the Aluminium with the holes out, and the airflow into the case easily doubled, as it is very restrictive. Removing said fan grill also eliminated the slight "whooshing" sound the air used to make when being pushed through the holes. Overall I saw a nice 2-3C drop in system temps, and the air exiting the computer is now barley luke warm, compared to the hot air from before.
