well for the rads I don't want to run them between the pump and the CPU block since from what i've read with the whitewater block you want the max flow you can when it hits the block so the less restriction between the pump and block the better.

anyways even if ran some of it parallel will the Eheim 1250 or Hydor L30 be enough for that setup, if not should I get the Eheim 1260 or go 2 pumps, from what I read in most systems the extra flow rate of the 1260 is usualy wasted and all it does is dump more heat into the water, if 2 pumps would be better which way should I run the pumps, parallel or series, or since i'll have 2 radiators should I seperate the system into 2 seperate loops, CPU on one and the GPU, chipset, and HD's on the other?
