cain't tell from the Dell stockroom page how many USB ports are on 'em...
I see alotta DVI cards... is this a good option?...
DVI is Digital Video, and it only matters if you have a monitor with a DVI connector. It is a better cleaner and faster video signal.
I another year you won't be able to buy a computer or monitor that is anything else.
Are you replacing the monitor too?
On USB ports... don't get too hung up on that. Little USB hubs are cheap ($15) and can instantly expand how many devices you can plug in.
Mine only has two USB ports but I bought a hub.... got internet, camera, printer, extra printer.... all hooked up through there....
