Build a MAME Cabinet in 24 Hours

This is cool--exactly the idea that I had about a year ago. Take an old PC, load MAME on it, build a cabinet with the various game controls, and wha-la! You've got an arcade console with virtually every game ever made on it.

FYI, MAME stands for Multiple Arcade Machine Emulator--basically it allows you to run the code from virtually any of the arcade game machines on a PC--you just have to find the ROM files, which are available on the Internet).
