With everything installed and the El Diablo powered on the effect is very nice if you like blue LED's. The A+ logo on the front panel door lights up and the strip under it serves as the hard drive activity indicator. Both front and side fans illuminate as do each of the side vents. There are two adjustment dials, one on either side of the front panel, which control the speed (and light output) of the fans. On low they are barely audible and on high you don't hear much either, mainly just the sound of moving air. The side panel fan did emit a slight "rattle" on high however.
On to final thoughts and conclusion.
