Did you not hear about the google research regarding HD's? they tested 100,000 HD's and one of the conclusions is that if a HD gets below 30C it is more likely to fail, so I'd say the watercooler for the HD is not a good plan.

I really only have one thing to say: "Get a koolance system!"

I think someone doesn't understand the definition of the word "condenser". These are still radiators, not condensers, as there is no phase change of the coolant. Air conditioners and steam turbines have condensers because they take a gas and convert it back to liquid, by drawing off the heat and into radiator fins. A condenser then is basically a radiator that works with phase change, rather than just cooling a liquid.

liquid coolers are for jews
