Has anyone used a Mini-itx for an audio jukebox?  I know they have onboard audio, but also they have PCI slots or USB.  Is the on board audio good enough?  Or would I need some better sound then that?  If I do bump to something better, what is a good choice?
As for my plans, I roughly picture building something like a small touch screen which would lay on top of a rack stereo system.  So the audio would only get thrown to an outside amp.  I don't know if technically you would still call it a jukebox, but you get the idea.
