Couldn't you just use a wireless mouse and keyboard to control the comp placed by the system?

I feel that using an old comp(I have a few laying around) would work pretty good...but I still would need to invest in a really good sound card like M-audio. Having a unit like a Squeezebox or Duet would still give me the ability to use the digital out for better sound quality.

Weighing all the different options makes my head hurt a bit. I think I need to lie down now.

Cheers,
