AMD A10-based alternative to Mac Mini

Hi, all

I want to get something between a Mac Mini and Dell X51 to act as a media center and a gaming console for my TV.

I want to build it around AMD A10-5800K, because it's supposed to be relatively quiet, won't need an additional GPU and should be a nice value for gaming.

What kind of motherboard, case and cooling should I get to build the resulting PC as small and quite as possible?
