I agree with the Alienware case suggestion - inexpensive, but good quality. The face cover also eliminates the problem of having to find colored drives or painting your faceplates.
Some people claim the airflow is poor, but I get excellent cooling with mine using a PS w/ intake on the bottom (the default Directron 250W PSes have this), 80mm intake in front, and 80mm intake on the side blowhole (preinstalled as an exhaust, turn it around).
