David Clausen decided to celebrate the Mac's longevity by making something special. So, he gutted the case of a 512K Mac (the case is in great shape, by the way), then inserted the workings of a Mac mini and a grayscale monitor. Add to that a LS-120 floppy disk drive and a custom-built USB microcontroller (to use the original mouse and keyboard), and you've got one badass compact Mac. For more detail, check out the Flickr Set.
All because he wanted to "...experiment with creating a custom USB device." That's one heck of a device. Hey Dave, if you decide to sell these, let me know.
