I'm pondering if its even worth doing push/pull if you are going to use two big honking 420 radiators.
Having a second set of fans only marginally helps improve cooling on normal speeds (About 7%,
JayZ tested it recently).
It does do a little better when you have 2200RPM fans on there going full tilt, but with the noise, who does that..
My gut feeling tells me it should be fine if you run push in front, and pull up top.
Atleast thats how I intend on doing it.
Unfortunately im going on vacation next week, so no build blog just yet.
The good news is that Zotac's 1080 arctic storm card will be available when I get back.
(SINCE EVGA SEEMS RELUCTANT TO COUGH UP THEIR DAMNED 1080 HYDROCOPPER!!

)
I'm still on the fence about soft vs. hard tubing.
Hardtubing can look very nice and orderly, but its apparently a PITA to work with.
I kinda want to use EK's white flextubing with black anti-cinch springs instead.
..well what I REALLY want is transparent flextubing with some of mayhems white 'shampoo' liquid,
but I heard that stuff is pretty bad for your blocks and doesnt last long, so...
