Yeah, that purple thing is where the two side fans are mounted. There is then a 1/2" gap between that and the panel. The top fan has holes in the panel (as seen in the picture) but the bottom one does not. Some air comes in the holes on the bottom of the door, but not much.
As to the saw, not yet... *grabs camera.*

Only the most-modern technology is good enough for my rig. This saw dates to sometime in the 1980s. It is a 5/8" stroke and is capable of speeds of up to 3000 SPM. The blade I used was 32 TPI, ideal for cutting metal pipe according to Sears.
The advantage of a scroll saw over a jig saw is that the blade can be turned independently from the base, up to Â±45Âº, which is a handy feature if you do not want to be bothered to remove the rivets from the panel before cutting. Just steer around them!
