Ahhh
So let me see
1 - 3x140 ?
1 - 2x120
1 - 1x120
Is that correct
if so ....
Personally I would use three pumps, just a little pisser for the chipset with the single 1x120
3x140 GPU's and th 2x120 for the CPU
All on there own loop
2x120 I doubt would be able to hold down 2x 580's at a decent clock ...
I would also look to get as much Volume in the CPU and GPU loops to the tune of dual bays for each loop and just a micro or even a fill port for the chipset ....
