I've never used a water cooler. How do you check for leaks without ruining components? Do you use water or vegetable oil? Do you have to have one for every heat producing component? Which ones, using the example of strider17's new computer in the list David posted.
I have a custom loop, and just use distilled water with a few drops of PT nuke and a strip of silver to prevent algae. I've never had a leak, but bear in mind that the loop is very low pressure, so if it doesn't leak right away, it's probably good forever. Some people use pre-mixed fluid, (often colored), but it can get a bit mucky, IMO.
My loop water cools the CPU and (2) GPU's. Some people also water cool the MB chipset and VRU (voltage regulator).
I think the All-In-ones I was suggesting come pre-filled from the factory, so you just install them and go. Most of them just cool the CPU, but some can be expanded to add GPU'S.
