The CM Storm Scout case is absolutely amazing. I have one, and I love
it. It has a bottom mounted PSU, matteblack interior and exterior, tons of drive bays, no stupid door on the front, tons of front ports, absolutely top notch cable management, and great airflow. 140mm in the front and back, 180mm on the top. Vents on the black tinted sidewindow for 2 more 120mm's, if you want them. Mine pulls a good deal of air in even without the fans on the sides. Also, it has a handle on the top, so it's awesome for LAN parties, and really made building it a lot better.
