I see what you mean. This case has horrible airflow and no side intake. I just removed the side and its already 17 degrees cooler! Was at 85 or so now 68.

Wow I guess that answers it!  The other case has perfect airflow, 2 front intakes, 1 side intake, no obstructions whatsoever, removed all lower bays. 2 upper fans blowing out and one in the rear and it runs at a constant 65ish degrees.

I can't believe I paid so much for that case back in the day!
