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...
