Rather than try to add WiFi and USB to a somewhat noisy TAM, I'm thinking of retrofitting it with the guts of a PowerPC Mac Mini and a 12-inch touchscreen. That'll allow me to run Mac OS X 10.4 and current applications, and connect to my home network easily.

I want to use it to play music and stream audio so I'm mainly looking for info about powering and connecting the Bose speakers & subwoofer to the Mini. I'm okay with reaching around to the back to trigger the power. If someone knows of a touchscreen that fits the TAM case I'd love to know that, too.

One more thing I'm considering is to build a Keyspan IR port into the case so I can use a remote with it.
