from what i have been told watercooling really will not give you any benefits over aircooling unless you are overclocking i bought an evercool system and then never installed it. you can get a HDD block to cool the HDD it will then mount into one of your cd drive bays. the only "real" benifit i could see from a liquid system was the fact that it was suppose to be quieter, however when you take into account that the radiators use fans i think it would be just as noisy as a good air cooled system, however they shure do look great in a case with a side window and in the clear acrylic cases, but since the acrylic case do seem to generate static electricity and scratch very easily i would not use one of them.
