You're actually serious?

water cooling should really only really be used for overclocking or otherwise if you have money to burn.

water cooling is more effective but if you just want to lower the dBA down on your pc then try:
1, changing to larger 120mm silent case fans,
2, changing the heat sink and fan system on the cpu
and to help lower the temp also try
1, making sure all internal cables are tied off neatly to allow airflow
and
2, using a larger pc case made of ali

water cooling isnt for everybody, it cost money, and has to be done properly by a competant person otherwise if you dont know what your doing you will flood your system and blow the lot.

as an example i have a thermaltake shark case, which has two silent 120mm fans and a honeycomb side panel, and the temp and dBA in my case is perfect. i am thinking of modding it with a new side door that will fit a 200mm side case fan! to add even more air circulation and still keep the noise down.

when i do get the pennies i will go for water cooling but that will be to overclock the system

the point is do a bit more research before shedding loads of money on water cooling and think about whether a few fan changes can help

water cooling is silly

i run a pentium D extreme, 3gb of ram, 2 180gb disks, 2 dvd writers, a floppy, loads of PCI cards and a radeon x1950 512mb. Runs all fine with air cooling fans and heatsinks. Can barely hear it.

Cpu tunnel on the front to the back - 2 80mm case fans for that as well as a single 80mm case fan also blows down onto the northbride and ram (which have heatsinks), 1 fatass cooler/heatsink on the gpu and 2 fans blowing/sucking the hdd bay. i use round cables or SATA only. And a cpu cooler of course

7 fans in otal and its barely audible - use good qualilty slow fans, and big, good heatsinks and compound/
