Liquid cooling will not improve thermal issues for the Mac Pro.
The only benefit to liquid cooling is that it has the potential to remove more heat from a very small area (a chip). But heat is heat, and all the heat ultimately has to be transferred to air regardless of any intermediate steps (water, vapor). To get more heat out, a larger case is required that can support more surface area for that heat transfer to air, regardless of whether that's by a larger heatsink or a larger radiator.
People who want more power (heat) are missing Apple's point about the Pro. The Pro is designed to be an almost invisible desktop machine: small, cool, quiet. Double the power and a new pro would be twice as hot and likely four times as noisy. Your office or den will become an oven and the noise will drive you nuts. I'll take small, cool and quiet, thanks.
I have my machines - a cMP and a Linux box - in my garage, where their enormous heat output makes it a very toasty space (having my relatively low power consumption linux box running full-blast in my office for even an hour was awful!). I also used to have a liquid-cooled Mac - never again!
