I would go with a HAF X. Just got one last week and LOVE it. The GPU cooling tunnel is great w/ a quiet 120mm fan.
Dropped my GTX580 GPU temps from 85c to 65c running full load and it isn't too moisy. White noise drives me nuts so I am not too tolerant of loud PCs.
Plenty of room for any type of GPU expansion or water cooling, as well. It isn't the cheapest and it is kind of ugly... but DAMN it does what it is supposed to.
