Hello guys,
 
  I was just wondering if anyone here could help me out I'm planning on water cooling both my GTX 480 SC possibly my X58 Classified 3X SLI 760 and my i7 920 processor.  I have a 800D Corsair Case and would like to know what kind of rad I should look into.  I've been looking at the rad below.  Has anyone used it before? If not could you suggest a good rad for my case and my cards?

My set up is not too different component-wise; see my sig.  I believe your case has a little more room for rads.  I mounted one on top internally and one on top externally like this (hope the pics loaded):


 
 I'm using standard 120x25 fans.  Temps are in the mid to high 30's idling and with folding (GPU's and CPU maxed out) around 60⁰ C
 
Skinnee evaluated rads a year ago.  Here's the link.

I chose lower resistance rads as I did not want the rads to impede flow through the GPU's, MB, CPU.
Good luck with your build.  It's been lots of fun for me.

Counteragent....got pics of your setup.  I was considering similar when I was building.

Lots of great watercooling builds using the 800/700D cases. Look in the build section for some good ideas. Here is my dual loop setup in a 700D with two 480s in Sli. Which will soon be upgraded to a Tri-Sli as I got my 3rd 480 last week.
