Last year, I cobbled together a draft of a guide to setting up a media server on a Mac Mini. It's intended to reflect what the consensus is around here, at least as to the basic issues. I've now revised the guide (with the help of a couple of folk here at CA) and have included a number of screenshots as well, which I hope people will find helpful.
It's free, and it's available at the iTunes Bookstore.
As CA gets a lot of questions from newbies about setting up their first music server, I thought it would be useful to compile a list of answers, which can be found here. (It's a link to Scribd.)
If you're a newbie, please let me know if this is helpful or not so much. If you're an ... uh, oldie ... please feellet me know about any errors or to suggest new answers.
UPDATE: I posted a revised version today. Same link at Scribd.
