If nothing else, the ProtoMAME #5 is commendable for being a fully functional Mac-based arcade cabinet. This machine uses a flat-panel iMac that’s stuffed into a custom built cabinet. It features a mini-upright design along with a decent sound system – including woofers, speakers, and tweeters. Additional pics after the jump.
From the article: “I’ve also been playing a lot of Robotron on it. I can’t say I’m very good at Robotron (I’ve only broken 200,000 twice) but you do need to hit 100,000 to even get on my high score board. It is a very good Robotron machine.”
