another pc question: can I get away with a decently specced PC is a small case? My current (and old ) pc is a big hulking thing. I'm planning on getting a new machine soon, probably based round the "hard choices" advice. But if I stick a speedy i5 and new GPU in a smaller case, am I going to have cooling/noise problems?

I don't really play high end shooters, although I would like to play Sins:Rebellion on a large map with extra shineyness :)

I like quiet pcs :) Reckon I'm maybe best just sticking with big fullsize tower cases?
