Oh sure. (Actually I'm living on a windy coast at 55N, furthermore my house has electric storage heating so "waste" heat from computers during the winter months has a very low cost). > > My moral is: don't over look the benefits of the "waste" heat if you > live in a climate where you have to spend energy to keep warm.

I have to switch off some (less productive) systems during the summer just to keep my indoor environment reasonably comfortable. I don't have air conditioning - the climate hereabouts doesn't often warrant it - but running AC to dump waste heat from computers would approximately double the effective cost of the energy consumed.
