watercooling loop help needed

[deblow]

I'm planing my next build, due to the size of the build I will be using up to 4 pumps, 2x triple RADs, 2x 400mm+ RES.
Going to be cooling the CPU, MB, possibly 2 or more GPUs & maybe 2 to 4 HDs

If I go with the 4 pumps I'm wanting them positioned in a square shape as show below,
Can anyone tell me if the plan I below will work for my setup or if there's a better way to do it.

Wouldn't the rads be better after the MB/CPU/GPU/etc then res , That way you have cooled water going into your pumps too.

Apart from that the only problem I can think of is balancing. 2 of the inline pumps could be pumping slightly more/less than the other 2. If you see what I mean.

Good thinking Pete, but i can only do that config if done like this - , Pump - MB - other - RAD - RES, thats due to the build & placement of items.

still thinking about the balancing, my heads a bit messed up with all the meds im taking atm lol
