DynapowerUSA Blackwidow Case
 

Internally, the back is standard with a couple notable exceptions. First, there's a custom PCI retention system. Second, the fan snaps into a pre-installed bracket. The front has provisions for 4x 5.25" bays and 6x 3.5" bays (2 external, 4 internal). There are also two blue retention clips for quick installation of a pair of drives. Lastly, there's a spot for a 120mm intake fan. It draws air from the bottom of the case.
