My media server currently resides in one of these beasts, and makes me very happy. I currently have it full (12+ hard drives, 4 opticals, A64 4000+, Antec SmartPower 550W) and it is humming away nicely. The case is a joy to work on, really easy to reach everything, and plenty of expansion options; but it is not a quiet case. This is not one I could make quiet regardless of the components. The huge grill on the side and the entire front facilitate massive CFM from arrays of fans, but directed airflow paths at low velocities will be diffused in no time. The thin aluminium is great except that is resonates quite a bit (despite the thin aluminium, there's no way you'll lift it decked out, so why didn't they go for steel?).
Just some thoughts...
