Here's what I'm after... unless you fine folks have a better idea.
I have a equipment cabinet (receiver, dvr, etc. etc. etc.) It has an open back, but the back is only about 1" from the wall... enough heat is NOT escaping and I feel the cabinet is too warm inside. So much so, that I leave it open, which defeats the purpose of everything being hidden (duh!).
What I'd love is a muffin fan with some kind of flexible hose/tube... (the hose tube would be the "out" side of the fan)...
Has it been made or should I just fabricate it?
