$5000 Watercooling Rig Help plz ... !?

Hi, I have a $5000 budget for a watercooling rig I am undertaking. This will be my first time venturing into watercooling, so please go light on me. I have some parts picked out and would like some expert advice on weather or not the parts are correct and recommendation on any parts I am missing and anything you feel is better for my money. I have a 46" 3D TV so I will be going Nvidia , 3D will cut my frame rates in half so I need the extra power for these new games like The Witcher 2 and what's to come ... here's the build ...

CPU ... i7 2600K $330

Fittings .... I don't understand this part at all , if someone could pick out the proper amount, or advise me.

Vid connectors ... 2 x Koolance VID connectors $50

480 rad enough ? It would go on the bottom of the case with 4 x 120mm Yate loons ..

$900 before proper fittings/barbs/clamps. Then I use distilled water with a silver coin in the res ?

I don't know the orientation of where all the parts go etc. But I would like to make sure I purchase the correct parts and the proper amount of fittings which makes me go cross eyed. Then I can play around from there!

I'm also thinking of going 800D or Haf-X with a 360 rad and an Asus Z68 Deluxe board then SLI GTX 590's , if that's an easier route.

Saw this and it looks nice!
