Thanks for the advice. Here's what I've done. I put a 2" passive intake in the bottom. I have a 6" oscillating fan right inside the passive intake and pushing air to the top where I have a 4" 80cfm cpu fan for exhaust.

I still have to install the 80cfm tonight. My total area is about 8.5 cubic feet - will the 80cfm's fan be enough to bring down heat?
