Despite having a pair of more efficient four-core Intel Xeon 5300 “Clovertown” processors, the 8-Core Mac Pro certainly doubles as an excellent space heater in sub-30-degree weather. Throw in a pair of 30″ Cinema HD Displays, and you’ve got your own aluminum convection oven once the machine’s fans kick in every so often.

Seriously, I don’t need central heat with this thing around. Though, I did also say that back when I had the Quad G5. However, that made the house a little too warm and probably consumed more power than your average space heater would anyway.

This, though, is just right. So nice.
