My airflow's fine. I have 5 fans: Intake on the front, intake in the side panel, 2 in the back, and one on the ceiling, as well as the heatsinks for my processor and video card. I almost never feel hot air coming out, and I've opened up and felt the heatsinks and they've never been too hot. Of course, I haven't tried overclocking yet. I do have a side window, though, so maybe I'll try and clean up.
