Hi Baylorgator,
I have been looking at the Squeezebox or the Opus Musica as my main options. I ruled out having a computer in the stereo cabinet because it was too hard to figure out how to do a remote. Your Mac Mini option sounds intriguing. Questions:
1. Is the remote infrared, or RF?
2. How noisy is the Mac Mini? Note that the Squeezebox is completely silent (no moving parts). The Musica is said to be pretty quiet (no fan, and hard drive chosen for low volume). If the Mini has a fan, it may be considerably noisier than the other two options.
Finally, comments on the network piece of the squeezebox. First, why do you think you'd need to leave the door where your computer is stored open? Second, can you run wire and skip the wireless part?
Cordially,
Eric
