A few people have mentioned these things already but here are my 2c on what would make the perfect case.
1) Keep the heat generating components separate from each other. I would probably want 1 section for the Mobo and another with the PSU/hard drives that are separated from each other. No need to have the HD and PSU warming up the CPU.
2) Keep the fans to a minimum, think about airflow. I'd say you only need 2-3 120mm fans in the case TOTAL. 1 would be on the PSU, blowing the hot air from the hard drives out of the case. The other 1 would be an intake fan for the CPU, and finally perhaps 1 more for an exhaust. So we're talking 2-3 120mms TOTAL inclusing CPU fan and PSU fan.
