I currently use the Koolance PC3-725BK
and its a great case. Has a "perforated" design which allows alot of airflow. It seems they don't carry it anymore but there are a couple of places that still create them from the lian-li case and the koolance unit such as Unique PC Gear
and Platypus PC
. Koolance may not make the very best pumps available, but I think there is something to be said for style as well.
