If you consider yourself a gamer, then you likely have a few NES cartridges lying around the house. If not, leave now. Rather than letting them continue to collect dust, 8-Bit Memory turned a bunch into external USB hard drives. You can get whichever size and style you want and you can even get USB 3.0. For example, a Dr. Mario Nintendo game cartridge will cost $130 for 500GB, $150 for 750GB, or $180 for 1TB. There are an assortment of games to choose from and if there’s something you don’t see, you can just ask for it.
