I know it was a joke but it's been done.
Well, I don't know about the freezer one but some guy, a while back, put his P3 mobo in a mini-fridge. Put everything thing in while the fridge was room temperature. Ran cables for his CDROM. (Don't remember if the hard drive was inside or not). Sealed everything up with rubber caulking (or some such). Allowed the fridge to come down to minimum, stabilized temperature, about 3 days. Switched on the PC.
Since the fridge is sealed no moisture can get in to produce condensation. It should work for a freezer.
