Very true. For my setup I had hoped to move enough air outside to get rid
of the heat, but nothing more. Maybe a few small blowers, not huge fans.
I could never understand why they don't put return ducts in every room of
the house that has doors that might be fully closed :-)

Sweet! When I had all of our systems in the dining room, we never turned
on heat until it got to about 28 degrees F outside. It was all in the
dining room near the stairs. You could feel the heat rolling from the
downstairs ceiling up the wall going upstairs.
Probably 25 amps of computer stuff humming (Indys, Sparc 20s and AMD
Athlons at the time).
