NZXT Adamas Premium Aluminum Chassis
 

"One attractive design feature of the Adamas is the beveled fins on the top,
bottom and front of the case. This is mostly cosmetic, as the 3mm thick outer
panels do not require the extra rigidity, and the abundance of active cooling
(4 x 120mm fans) make the fins completely useless as a heatsink. It does look
very cool though and should appeal to those consumers looking for something
very unique. The power and reset buttons are in a standard location on the
front of the case, as well as a blue power LED and green HDD activity LED."
