Someone on here has pics of a build. i'm seriously considering it.
There are smaller, overheating is related to how many changes of air you get per minute, i.e. the ration of fan cfm to space in the case. Imagine a really big case with tiny fans vs a reall small case with big fans, which has the most fresh air for cooling?
I have little opinion, other than really liking the fractal design cases. not hearing anything bad about the antecs though, i've got a P180 B myself. You have to figure out what is important to you, expandability, size, cost, noise? and then you can work out what you really want.
