Hey Jpond,

Here's a few pictures that may help you figure out how to setup your cabinet.

Looks like I did force air in, the input is down at the bottom and the duct fans are blowing into the cabinet. When it was too hot, I added the big blue fan on top to push the air in. The exhaust was the 2 bathroom fans at the top going to a common exhaust. All of this was controlled by the CAP controller you see on the inside. The 3 switches at the top enabled/disabled the fans. For the light, it's the two vents toward the top; there was a 6" duct fan inside to put air through the closed hood, controlled by the lighting timer.

Peace,

Farmer Rich
