True, but if he doesn't want to hassle with different parts from different manufacturers and wants an all in one kit that will work great out of the box, even having to assemble it as that's the whole point and where most of the fun lies imo, the Wsiftech kit is the place to start. I think that for someone that hasn't messed with water cooling this is a good place to start, but yes we could recommend parts and you can pick and choose to your liking.
I'm personally digging the HeatKiller 3.0 for CPU waterblock if your interested

And the back plate to go along with that.

Radiator Fan Housing (if he decides to mount on the back of his case unless he knows where he will be placing the radioator already)

Tubing X10ft (just in case)

All in all he would be spending about $440 not including shipping and not considering he might or may not be able to pick up all those parts from the same place otherwise shipping will really make that jump to probably near $500.
I really think the Swiftech kit is a great place to start unless he doesn't mind spending the amount up front to really custom build his water cooling setup. We can continue offering suggestions on parts I guess, but that hetkiller block is awesome from what I keep hearing.
