I got my waterblock from
www.Dangerden.com i think it was their maze 3 got my radiator from them too
got a pump from the net... same kind they were selling at dangerden.. and some tygon tubing from the hardware store...
and i made my resevoir/filler with pvc from the hardware store...
the biggest weakness with my water system is the radiator is too small... when i was just in the planning stages i thought i wanted the whole thing to be 100% internal so i went with a little 80mm radiator... i wish i had gone with one that fit 2 80mm fans... if not bigger...
