The Ultimate Arcade II Cabinet. Clever idea. Start with blank cabinet box, add your own controllers, PC hardware, software, cool peripherals and bits and bingo, yer very own custom arcade games console.
Or you can short circuit the process and buy a ready built UltraQuad, complete with powerful PC, 4000 games on-board and a huge choice of controller add-ons for around $3900.00.
Check out the cheaper Dell powered models on eBay too. Obviously big business!
