Are the graphics upgradable? What slot type does the graphics card use? If I were to upgrade the Nvidia 6150 128MB on the Ori system to the Nvidia 7600GT 256MB as used on the Gaming system, how much would it cost for this upgrade and do you offer the DVI to DB9 (Standard VGA) adaptors? My monitor does not support the DVI connector.

I have a spare Audigy ZS2 7.1 sound card kicking around. Would I be able to put this into the Ori, and disable the onboard sound?
