If you have a soft spot in your heart for old-school video arcade consoles — not to mention a couple hundred dollars and the tech expertise to dismantle a netbook — you might want to check out the Nanocade Kit. For your US$229.00 plus free shipping (prices slightly higher in Canada and Mexico), the company will send you "23 pieces of high quality laser cut acrylic" which you then glue together to make this adorable tabletop arcade-game case. Then the REAL fun begins: assembling the electronics guts (using either a nettop or netbook computer or ITX motherboard, video screen, and joystick controller/interface) to run your favorite game software.
If that seems like a lot of work (and money), don't worry: designer Rasmus Sorensen's also offering a prebuilt Nanocade case. Only US$350.00.
