Dude, I would be happy to help you build a water cooled rig.
I've been building water cooled rigs since 2003.  And I've been sleeving my own PSU's for nearly as long.  Also I do all of my own custom wiring.  I never use the cables that come with the PSU.  I use custom 22 AWG and 18 AWG wire, and I crimp new connectors, and custom sleeve it. 
Here's an example of mine:

I even have extra water cooling parts, and extra sleeving.
PM me, and I'll come to Brooklyn or you can come to Manhattan, w/e is easier.
