basically, i want a small a case as possible (i travel with my pc a lot), but with the Q6600 @ 3ghz i doubt my tuniq tower would fit in, basically atm, my specs are antec sonata 2 case (which is awful for transporting), 7800gt, 520w modstream, gigabyte DS3, 2gb geil low latency pc6400, raptor x 150gb, e6300.
My e6300 is at 3.2ghz atm, obviously as the Q6600 is quad core i wouldn't need it at 3.2ghz, so 2.8-3.0ghz would be fine, and im sure ive seen specs in a SFF case with quads @ 3.0 - 3.5ghz
