Hi Avta,
Thanks much for the suggestion, but I'm just a little leary of those kinds of things, though it is not based on any real world experiences, or at least negative ones. However, I'm totally comfortable now with the mac mini and I just happen to have an extra one I can dedicate to this system now, so that's what I'm going to do.
I originally got the PK-100 because of it's appliance nature -- and mostly for my wife, but showing her that she can control the music on the mini just as easily as the Auriliti, using her iPhone, she's ok with the change, and there will also be no need to have this computer on the network -- using a local FW drive for music storage.
