Here is some pics of my enclosure. I have the fan venting out the bottom through the box and the intake coming in through the box to cut down on noise. The box is 1 1/2" foam. I think this weekend I may change the intake vent from a 4"to a 6". The fan is a 6" 290cfm from Vertex and I think the 4" intake is a little restrictive the air is really sucking in.
