Oh, BTW...
I would probably search through peoples garbage or go to a junk yard or call local refrigeration places to find info on this first.. before I go sinking 80 dollars into a frige alone.. plus another 50 to 60 in a case.. that just would NOT work for me.
I'd really go stellar crazy if I found a place that had a nice system sittin round that would be ready to roll for cheap and work great... but that's everyones dream

.
I really DO NOT want to use more then 200W an hour on my new cooling solution... I'd like to target 150W though.. that would be awesome.
Edit: I am going to be running under 1 gallon of water most likely.
