I have a 2.8g(northwood) p4 on my socket 478 gigabyte motherboard at the moment. I am planning to soon buy a 3.4g E (prescott) socket 478 processor to replace my old one. I hear that prescott processors run slightly hotter, and i would like to overclock it, so immediately i began thinking water cooled system. I planned on buying the water cooling system that thermaltake has out now, Bigwater. This seems to be easy to install, looks cool, and has everything i'd need for a watercooling system, not to mention it is affordable. I also wanted to use a Peltier cooling plate in addition to water cooling, though i didnt want to attatch the plate directly to my processor for feer over overheating/condensing. I wanted it to be away from the motherboard. I began thinking and i came up with the idea of having the CPU waterblock attatched to the CPU normally, but also have a sort refridgerating unit to actually chill the water instead of the processor. This would be composed of a Peltier with a cpu waterblock on the cold side, and a stock p4 heatsink+fan on the hot side. I was reading some articles and i read in one that in order to have any kind of productivity with cooling a processor directly with a peltier you would have to get one that was 200 watts+. I didnt want to drain that much power from my power supply, and the 80 watt model seems to suit my power supply best, so I was thinking of using the 80 watt model in this cooling unit. I am new to this and i have som questions: Is it even a good idea at all? Will the stock P4 heatsink be able to sufficiently absorb the heat thrown off by the peltier? Will the water get so cold that it might freeze? If that is the case should i use water diluted with anti-freeze? What is the easiest way to wire the peltier to my power supply? How should i go about insulating the peltier so it does not get wet?

I was thinking the system would run like this
Pump -> Cooling Unit(Waterblock, Coldplate, and heatsink combined) -> CPU - > Radiator(comes with bigwater kit) -> VGA - > back to pump
