Demon-II from EBCcomputers.com for $40.
No psu, but two fans (red and blue with matching LEDs, blue intake, red outtake) and blue LED frontpanel.
Not too shabby for the price, plus I've got no back cover for the mobo and an empty floppy drive (my peephole) so I get 1337 coolage.
Can you say "breathing room?"
