I am definatly building the TEC chiller regardless of use. I think I am going to get 2 - 245/320watt TEC's off ebay.

That should run about $50 after shipping. I might pick up power supply as well. I already have 2 sufficent one's though.
I am going to try the direct cooling approch first and then maybe a copper block set. Will see how things go once this new ProCooling site is setup....
