Having seen Rick Galinson's paintball minigun project, I'm even more convinced that there's no chance in hell I'd put goggles and some camouflage gear on and face the barrel of one of these things!

What makes Geek Seek’s minigun PC, well, a minigun, is the DIY touches, from the rigid liquid-cooling tubing with a D5 pump/reservoir combo to the custom-welded steel frame with acrylic accents.
