We have seen a few of these NES cartridge hard drives before on Geeky Gadgets, the latest one is this cool Super Mario Bros 3 NES Cartridge Hard Drive.
The Super Mario Bros 3 NES Cartridge Hard Drive comes with a 160GB SATA hard drive inside, and connects yo your PC or Mac via USB.
It runs off USB power, so there is no need for an external power source, if you want one they are available for $119.90 from Etsy.
