why stupid though you need to say why? im not messing around im an engineer by trade so like coming up with mods
Because if you bring the water temps down below the ambient room temperature you'll get condensation everywhere and you don't have to be a genius to work out why water in a computer is bad.
If you wanted to do this seriously you'd have to insulate all your hoses with foam, grease up your cpu and cover the mobo in plasti-coat. The compressor would also need to be fairly powerful to work continuously and the condenser would need to be big enough to remove the extra heat you're throwing at it. Also having a fridge on constantly would A. be noisy and B. the compressor would kick out loads of heat.
