[Jake Howe] brought his 1984 Mac up-to-date by cramming new guts inside of the classic case. The goal from the start was to run OS X Snow Leopard on the machine without altering the externals. He heated and formed acrylic around the original CRT screen to make a bezel for the replacement LCD screen. The floppy drive slot was used to hide an SD card slot and USB port. The original serial port openings were even outfitted with their own USB ports. In the end he did a brilliant job of hiding the Hackintosh mini-ITX board and components inside this iconic enclosure.
