There is a saying, "friends don't let friends buy Thermaltake", If your serious about water cooling then I'd suggest doing more home work. for your money you will find better products that will out last the computer your using.
Again all that is if your serious about over clocking/water cooling. There are some great complete kits that will out shine the one your considering. example(I know yer an ozzi so the prices are way different for you) just look around localy then...../Rant
