by cake box do you mean IPC style?
Well..., I don't think you would get usable life out of it, those
machines aren't exactly green, and if it is running one of the older
disks, those things are power black holes.  If you had a software
interface, so it immediately did a clean shutdown, it might work, but I
doubt it would be worth the hassle, what do they need? +- 12, +5? 
that's either a 24 volt batery and 3 regulators, or a twelve volt
battery and a switching supply, either of which would add heat to an
already thermally challenged case.

Just my opinion, but you'd be better off getting another case, or maybe
an 811 case, and building a matching external power supply.  You could
actually take the supply out of the computer, whic would help with heat,
and build the supply and battery back up in a separate, matching,
stackable box.  You probably could get another disk in the computer
also.
