@Graphite8five: You could use a pump and radiator combo for that. Swiftech has a 140mm radiator and pump on sale for $85, just get the AIO set. It's priced $5 lower than just buying the radiator/pump alone. Here's a link
http://www.swiftech.com/H140-X.aspx I upgraded from SLI Hydrocopper 780's to single 1080Ti FTW3 with waterblock. I will be giving the 780's to my nephews, one of them will be hooked up to the MCR140-X Drive.
Here's a link to the just the radiator/pump
http://www.swiftech.com/MCR140-X.aspx remember you get more items with the AIO kit, hoses, clamps CPU block, filled coolant, thermal paste, 140mm fan, and a fan distribution block (PWM splitter). They have a picture of the setup you describe. Doing this setup would be a little convenient in certain situations.
Have you seen the tear down of the FTW3 on Gamers Nexus?
