If you are planning on cooling your cpu and 3 GTX580s you will need at least a good 480mm rad because you are going to be putting out a ton of heat that needs dissipating.
For a loop you need enough tubing, a reservoir for each loop, a good pump for each loop, waterblocks for each part being cooled, fittings for all parts.
All of these parts will take up a large enough amount of space, thus a large case is needed, which what the Corsair Obsidian 800D is. The Obsidian is not required to watercool, but a case large enough to fit all of your parts is highly recommended.
To be honest, if you have never watercooled before I do not recommend building this intricate of a loop your first time, there are simply too many things that can go wrong if you mess up a single thing. I would start smaller, say only cooling the cpu and go from there.

This is only partly true. The stock Obsidian can fit a 360mm rad up top, with modification it can fit a 480mm rad.Edited by lithgroth007 - 3/1/11 at 10:37am
