I have to say the mac mini is very tempting but dunno how well it'd handle recording if at all?
It'll handle it fine :) I've seen an old MacBook (the white ones), record 12 tracks (full drums, guitar and vocals) at once with a Digidesign 002 and an OctoPre, and there was no indication of things going south at all-- very reliable.... i'm sure a Mac Mini would cope fine with those, they can certainly handle 2 track recording, as we've been using them for tape-transfers here at work :)
Edit: Johnny Mac, do you mean that it won't connect to your Wi-Fi network, or you can't get anything happening with the Airport at all on the machine?
