I would recommend the Lone Industries L2, a 4.5 liter case. Very small, dual slot low profile GPU, two 80mm fans, two 2.5 inch hard drives. It does require external brick power. But maybe you should consider the bricks, cases with internal PSUs such as SFX are going to be much larger, noisier, and probably less efficient than a brick. I own the first gen of the case, and I think it is awesome.
