I just got a little Atom-based Intel board to play around with and it currently resides in a rubermaid container as its case. I've also been enjoying the new Heineken draught kegs, so I have a few empties sitting in my kitchen floor. This led to the obvious question:
Can a little Atom motherboard
fit inside a Heineken Draught keg?
These new Atom based boards are little mini-itx form factor, that's ~6.93x6.93". The little micro ATX power supplies are ~5x4x3" and a hardrive is ~3.5x5x1". So it might be just a tad to close on the diameter to be able to slide the motherboard right in.
That would be a pretty sweet case though...
