Colin Charles has an interesting article at the Red hat magazine on Installing Fedora Core on the Mac mini. He summarizes the installation of Red Hat Fedora on the Mac mini:
A pretty swanky mini box! That’s what the Mac mini is… tiny, aesthetically pleasing, and great with Linux. Save for the wireless, where a USB dongle might suit, everything pretty much works out of the box with Fedora Core 4 Test 3.
Mini servers, anyone?
