It's fairly difficult to upgrade the GPU in those small-form-factor PCs. Any serious upgrade will require you to upgrade the Power Supply as well.
The default config should support dual monitor graphics already. Is there any reason why this is not sufficient for your needs?
While it currently supports dual graphics, it only has HDMI and via. Ideally I'd like either two HDMI or one HDMI and one dvi. It would also free up some system memory. From what I've been reading, the issue is the 65watt power supply more so than the space constraint. I just figured if if I can upgrade it for $50 or so for both monitors to be digital vs the one vga, then why not?!
It's a nice thought. If you are worried about memory, that can be upgraded easily.
Other thought: you should skip the usb display adapters, they could allow another dvi/hdmi port, but they will be lower quality than your existing vga since they use heavy compression. They also take a lot of cpu power.
