I recently got a new case for myself the its a Cooler master HAF case, I really like the fact that you can easily hide the wires inside of it, the power supply is also on the bottom. The air flow in the case is remarkable compared to my old case. Wish I had got one sooner. I also like the Hard drive tray they use its simple to exchange drives quickly.
It also came with two 120mm fans installed and I installed two more and a fan controller.
