MB for 6400+ Black?

Looking at building a new computer, need some help on motherboard. I'm planning on trying the AMD 6400+ Black Edition. Not expecting to run SLI, so that's not important, just looking for something stable with room to OC. Preferably not a microATX board though. Which chipset should I be looking at? Any particular suggestions? I'm also looking for a case with good airflow and decent room if you've got suggestions there.

get a case that you like, I accidentally recommended you an mATX board so this is my edit
