Building a CDR/CD-RW Appliance?

Fafhrd asks: "My father has developed a new hobby: He records music shows from his satellite dish TV, digitizes the music, and burns a CD to listen in his car. We tried digitizing to the computer as the show runs, but it's cumbersome, as we have to drag the computer across rooms to plug the dish box's Audio-Out into the sound board's Audio-In. So, I'm planning to build a device to do it for him. Just a ATX baby board with sound, a CD-RW and a big HD. Any ideas on what hardware is the best for this? Where can I find a case compact enough to house it, and not look out of place beside the VCR and the dish set-top box?"
