Typing this on my new mini running osx. Just wanted to say thanks again for all of those out there that put in their time and effort to make this possible, and making it possible in a way that was easy enough for those of us not nearly as tech saavy to follow.
I used the DellEfi, 2 USB method and a retail 10.5.6 dvd, went off without any problems and everything worked at first go - wireless, sleep (sorta), sound (with and without headphones). Installed latest security update with no problems. Anyway, enough of me - thanks again everyone, you rule.
