I like i7 from architecture perspective. High wattage for the cpu is ok as long as perf/watt benefits and temps do not exceed. I expect temps to be the bigges issue for i7 in server space.
Nopes, have you ever seen those server rack machines. Talking about air cooling, servers have the best and the noisiest (fans fans everywhere, front to back). 2 processors isn't much effort to keep cool, but 4 processors maybe..
