I think Kjetil is right here for most situations. There is some doubts
whether a top mounted fanless psu is better then bottom.

Anyway, the choice seems to be the p183 vs Factal design R3
http://www.fractal-design.com/?view=product&category=2&prod=48

It's hard to judge, not having the cases here, but to me it looks like
the p183 is HUGE... Qua looks and height I prefer the R3, but I'm not
sure the performance will be close to the p183.
