I have a i7-3770k, and a GTX 780 Lightning, in the Corsair Vengeance C70. I plan on getting a second 780 Lightning in the coming future, and would like to water cool all of these parts. Right now I have a Cooler Master Eisberg 240L Prestige water cooler on my Processor, and want to know what would be the best solution for getting a second 240mm rad in my case, without losing my HDD cages, to water cool the 780 Lightnings, or if it would be smart to run all three one the Eisberg?
