I managed to score a free Mac Mini a few weeks ago, but it ended up having a bad hard drive. So I took out the adapter and SD card from my last experiment, and threw it in the "new" Mac Mini to see if I could get it to do anything. Mac OS X 10.5 Leopard was installed on a Mac Mini (Powermac10,2 / Late 2005) with a 1.5 GHZ PPC G4 with 512 MB of RAM, using a 32 GB SD card as it's main startup disk. While I was recording this video I went in totally blind and had no idea whether or not this was going to work. I had never taken apart a Mac Mini before and I didn't even know what type of hard disk was in the Mac Mini. I got really lucky.
