First let me say I have no experience, I'm just giving an completely uneducated opinion.
Ok, I think it's a great idea. Especially if you put fans on the radiator inside the fridge. If ambient case air can cool a radiator, refrigerated air can do it even better. The air will be cold
instead of warm. Better yet, why don't you put your whole PC in the fridge?
Yeah, that idea even crossed my mind. I could just take the frame of a PC case, with the components and mobo mounted on it, and see if it fits. There would prob be space for a few beers in there too... condensation might be kind of bad though...
It was a spur of the moment idea, but there is no way i will actually be doing this. I just don't have the experience (or money, probably) to do a liquid cooling setup, let alone retro fitting it into a fridge. Thanks for humoring me though, and maybe one of you ambitious case modders could turn a minifridge into the coolest, quietest PC ever, with room for some food! That would be bad-ass.
Or I could just empty the fridge out, build a computer inside, make precise holes for the drives and rear I/O stuff, and seal the door. That would be one huge, heavy case. but imagine that, you could have a giant RAID setup in there, all kept at a chilly temperature. And I'm not footing the electrical bill here anyway.
See this fridge is just getting me carried away. I'll go build a decent air-cooled setup like all the other commoners...
