yes, yes it is insane, and totally worth it if you've got the money. one thing to note though is you could build an identical machine for about half the price (although you wouldn't have the cool blue color). but jeeeez, i don't think even falcon has a $13k system
Is it insane? Yeah. Better get a good computer desk too...throw in another $300-$1k...you'll be spending alot of time in front of it...toss in a minifridge and a leather reclining office chair, and you could trade it all for a car.
don't forget the hands-free telephone system so you won't have to take your hands of the comp...or better yet just get a secretary. (after all you can't spend 24 hours in front of your comp all day, you gotta get up to go to the john every once and a while, just ask him/her on the way out).
