Fangio,
If you are looking for a pre-built system, then you might want to take a GOOD look at MAINGEAR:
http://www.maingear.com/index.php
They have an excellent reputation, and are quite 'reasonable' for being a high end boutique builder.
They used to offer AMD based systems, but it looks like now all they offer are Intel based ones. That's not all bad, but I am a confirmed AMD fan boy and it pains me to see folks like Maingear ignoring AMD.
OH, and don't worry about what some folks are saying about that little fracas sometime back. You and I both know that the history books have it wrong, and that it was really "The War of Northern Aggression".
