Bottom line; Don't spend your money on any available vapor-phase unit. If you want to experiment with it, buy a mini-fridge from wal-mart for $35 (i saw one yesterday) and strip the compressor out of it, or make the whole fridge into a case--it's really not that hard. If you are just looking to supercool your PC to hard overclock, then look towards a liquid cooled peltier setup as this is a *much* more practical and cost effective solution and can run even colder than vapor-phase (i've gotten stacked 80w liquid cooled pelts down to -70f at idle -65f under load) but with a bit more expense for power supplies for the pelts. In any event, costs to build your own super-cooled setup shouldn't run over $350 for everything, including the case and power supply, and that's a far cry from $1000-$3000, ya know?
