Hey Everyone,
Looking to water cool both of my 780 GTX cards. I can only play Battlefield 4 for about an hour before they overheat. Already purchased the xspc front and back plates for both cards.
Have a Corsair case that doesn't have sufficient room to fit a big enough radiator so wanting to go External.
I can fit a reservoir/pump in the 5.25 Bay if needed or have it all external.
Found this on Frozen Cpu, would this be my best bet or are there other options?

Any help would be great.
