Thanks everyone. Lots to think about; I've read a couple different results others have had with different pelts; seems most folks are using the 156w pelts for CPU? Is that because of the waste heat you have to deal with?

Also read that the 80w pelt of the GPU is no more effective that H2O; so what I'm going to do is get the Swifty waterblock, coldplate and gaskets and run only H2O on the GPU first, and if I'm not satisfied I'll buy a 130 pelt for it.

The reason I went with the 226w pelt for CPU is because thats what the Swifty uses, and I got a good deal on a MCW462 so I was just going to buy the TEC conversion for it. Do you guys think thats too much pelt? What can I expect the difference to be between a 156w and 226w pelt?

Looks like running in parallel is what I need to do; thanks prandtl, I think I read somewhere that a guy called Swifty about running both on that meanwell and they said no problem, so you are probably right. I also went and checked the specs on the pelt, and here's the specs:
Couples U max I max DT max Q max L ×W×H(mm) R(ohms)
127 15.2 VDC 24 A >67 ° C 226.1 W 50 × 50 × 3.10 0.48

Then this little note:
"Minimum requirements for a dedicated power supply: 25A at +12 volts.
If adjustable voltage is available: setting the voltage higher than +12V is not recommended. Lower voltage, can be safely used, down to 9 volts."

What about using a seperate ATX power supply? I've got a stack of old HP servers here I could snag the PS out of. I just have to make sure it will run 25A? Any sites that show you how to activate the 12v rail on a PSU without actually hooking it up?

Anyway, I found the recommended Meanwell S320-12 for $94, so if I can't rig a PSU than I'll just buy it. Maybe I can run both a 156w and a 130w off it; but I'm still trying to figure out what I need to get the job done. I'd like to get down to 0c on my P42.8c@3.5GHz. Also, I found a Meanwell S350-12 that runs at 29A; would this be a better choice?

EDIT: also, if I use a variable-wattage PS, does that mean I can run the pelt at different temps? Sorry for all the questions, I'm a noob with this stuff.
