You don't really sound like your into building your own based on your questions and responses, and since your budget is apparently limitless I'd say you need to hop on over to OriginPC.com, or Falcon-NW.com.

Origin is my favorite, they'll do just about anything you want for the right money including custom paint jobs, custom water loops, lighting, cable sleeving etc....
