coo. thatll come out good, i got the same **** computer(almost, i got a pavilion 7940, 1.0ghz, 133mhz fsb, 512mb ram, FRIED MOBO!!) i got a window in mine, a 120mm in back, 2 80's in front(drilled holes behind the bezel) and a 120 on the window over the pci cards. im in the process of getting a new mobo/processor/ram/video, and shove all that in there, cause that case is perfect for lan gaming, just gotta beef up that handle under the bezel(wait, is that a handle?) and do something about the cd lid on top being broken(gotta love younger brothers). but one thing to think about...also, have you checked the clearance on the back, to make sure that the plexi has a place to adhearse/screw to on the panel? o yea, one more thing, never uptate that bios....thats how my mobo fried, updated bios, ran for an hour, got a cpu overheat beep, pc still runnin, all fans shut off during halo, heard it quiet down, then smelt the **** cpu starting way overheating. atleast i was lucky and it didnt fry my harddrives...
