Seriously, is he sure he wants to do that? If you deck your rig out with everything possible, including monitors and such, you'll be paying a serious some of money. I mean, you can easily spend like 700 on ram if you want to do that. That is insane. On top of that, if he is going to do some raid configurations with the best hdds, which he would need if he was getting the best build possible, it would be insane. I would suggest putting some sort of budget up. If he doesn't, this will be like $5000-$10000.
