OCIA takes a look at the X-Sonic Aluminum Midtower Case in their latest review. Here's a snip.

Here we get an internal look at the drive bays. This case supports four 5 1/4" drives, two 3 1/2" external drives and two 3 1/2" internal drives. Below the 3 1/2" bays we have a neon green fan holder. An 80mm case fan can be installed here to draw cool air from outside and blow it across your PCI cards. Speaking of the 3 1/2" bays, the entire rack is removable for easy HDD installation.
