Yeah I haven't finished off my man cave yet but I might just stick it down in the basement anyways and duct the Mac Pro into my return air. Heat my entire house more efficiently!
I have a small office with my main systems I use for editing / creative content. With that, I have been able to reduce heating bills most winters by keeping the thermostat temp in the low 60s for the house, and only keeping the office warm (usually with a small electric heater). Since I have a Futon and some other light furniture in this room, I usually stop watching movies and TV in other rooms, and lock myself into this one for the winter months.
Keeping the door closed with normal lights and monitors on, kept the room near 78 degrees back in my G5 folding days! I actually have fond memories of the old folding days, as It was actually a winter from which I spent quite a bit less on power and natural gas.
