I'm way late to this thread, but if you want a smallish box to tinker with check out the Cooler Master Elite 110
or others in the Elite series, like the 120 and 130.
Nah, your not too late. I'm busy price checking, and I need to save up the cash first. Any and all suggestions welcome. I might end up getting a "pizza box" enclosure, and maybe a rasberry pi or arduino, with all kids of projects.
