Looks like an pretty nice system.

I'm an AMD, guy and I'd put in as much ram as I could afford. They are nice specs just as you thew 'em up there though. 

I agree, those 19' WS just don't look right to me. 

I have Dual 17" monitors on my main system now. I'd do Dual monitors instead of one  larger one. Especially one a wide screen. I usually have reference material up on one screen and work on the other etc. 

And a Dual monitor system is surprisingly easy to set up with windows XP. Just make sure your card supports it or you have room for another Video card.

As a side note Windows Vista is recommending 2gig of Ram to feed its needs. :P

Finally everyone askes; "Why only 17's not 2 19's, or 20's?"  My reply; "Ahhh..cause. I sit less then a foot away from them." :P
