I must admit that most external hard drive enclosures today resemble nothing more than a melted hunk of plastic or metal. Why not get a little creative and rip off Etsy user NES Box. He shoves external hard drives inside of old NES cartridges which give your computer a real retro feel. Need to back up right now? This Super Mario Brothers 3 hard drive can be had for $180 on Etsy and it runs from USB power. Not bad, but we’d recommend trying to make your own. An old Duck Hunt cartridge and a Dremel is all it takes to whip one up. That and a hard disk of course.
