try a fullsized 2 door fridge/ freezer~
and i dont think without seein it in person you can~
i would get a compressor of ebay~ BTW head over to the EXTREME cooling section
NO one is selling a fridge in the classifydes BTW..........
not realy due to the fact fridges are the size they are due to the fact that the cooling coils strech around the backside of the fridge to disapate the heat~ so.... nope..... are you trying to build a water chiller?
