This is my little mod to make sure my new 74GB Raptor is running COOL-n-QUIET!!
Its a small piece of aluminum angle I got from ace hardware and cut a couple small pieces off (one for each side of the drive) and drilled a bunch of holes in it and mounted them on the sides of the drive and tied it into a 5 1/4" drive bay with zip-ties and put a quiet 80mm fan (w/ blue LED's) in front of it blowing in on the drive and into the rest of the case.
