Securing a waterblock?



New Member
I am thinking of building a water block etc for my Athlon system,but how or what is the best way to secure the waterblock to the CPU.
Is it better if I remove the heatsink and put it straight on the back plate or remove it's housing and somehow mount it directly on the chip itself?? if so what do I do about the cache chips as they sit lower than the CPU on the PCB.In either case can you suggest good ways of clamping the waterblock
thanx in advance.......

Dodge this!
