When I was small, I dreamt of making an arcade-style cabinet for my Atari 2600.  Since my medium of choice for the day was cardboard, I pictured that.  I did once make a cardboard mockup of a soda machine, that was pretty cool.  Anyway, with the resources we have today, has anybody thought of making a cab out of an old system/computer specifically to capture the feel they would have had?  I'm not talking about emulators, I'm suggesting something like that NES cab that surfaced recently.  Besides using an Xbox/PS3/etc, has anything like this come about recently?
