I decided to stop building PCs when I got the Dell 4600 for my wife.
I ended up using it, since my DIY AMD PC stayed with my ham gear down in the (cold) basement.
I just brought up the AGP graphic card, so I could play COD on the Dell..
I'm going to put off the graphics & PSU for now, and decide what kind of display to get.
I'm thinking of a nice LED backed LCD that runs low power. A Viewsonic VX2453MH maybe..
