If you get a NF7-S then you'll be sorely disappointed. NF7-S only has onboard sound, no video.
The board you want is the NF7-M, but it does not have the Soundstorm technology for the onboard sound.
The onboard video of the -M is GeForce 4 MX grade so it shouldn't be too bad (don't know, i've never had an nVidia based graphic card).
