Wont work, sorry but you're about the millionth person to suggest this, a quick google search for something like 'PC cooling using a fridge' will bring back plenty of results. Basically fridges are designed to keep cool things cool, not to make hot things cool, it will just burn out the fridge, wont last long as all sorry.

Yeah, as Alien says, unless you live in the middle of the tundra, the moisture in the air will condense in the fridge so you would get water droplets forming all over the nice metallic contacts on the mobo...then the mobo dies
