Heck, I've already got my room heated up nicely. Usually 5-10*F warmer in here than the rest of the house. Thankfully my roommates haven't started turning the heat on yet.
Would be cool though to have a six node setup sitting on display in the living room.
Unfortunately it looks like around $100 total for a new mb/cpu/memory combo. Money I don't have right now. O'ell... stick with what I've got.
P4-2.4 - my work system, shouldn't have a problem there, no one else works on it.
AMD 1600, AMD1700, P3-566 - 3 of 5 computers at home
(I'd fire up the others but my old K6/2-200 isn't quite fast enough, and the P2-300 doesn't like the heat)
