Redditor IntenseCircusFire made this excellent replica Donkey Kong arcade cabinet out of MDF wood. He used plans from Jakobud.com and it took him about 30 hours to build. Along the way, he took tons of photos of the build process and he shares plenty of tips and equipment suggestions if you’d like to build your own. And since the computer inside the cabinet is running MAME, the free arcade machine emulator, his game selection is not limited only to Donkey Kong, despite the nice decal job.
