Now that looks like some unknown material from Area 51 eh ? The aluminum bezel door is held closed with magnets.

Behind the bezel door are five 5.25" bays and two 3.5" bays. On the left side of the bezel you can see the the front panel I/O connections, which are two USB ports and Speaker/Mic ports.

On the top edge of the bezel are the power/reset switch and power/HDD LED's. The LEDs are your typical 3 cent round LEDs, and that looks a bit cheap.

The side door is square with two meshes for fan intakes. The door is mechanically fastened with button head screws. The vents have mounting holes for users who want to add up to two fans.

The backside is fairly standard.
