I guess mine was a stand up arcade machine that I planned to build for many years, but never quite got around to.  Why and arcade machine?  Because I'm old and loved them as a kid and I'm basically a child 😁

I actually build it about 3 years back.  It has around 20,000 original arcade games on it, lighty-up buttons (that only light up if the game you select uses them, speaks out the current high scores when you select a game and then tells you what each button does for that game.  The joysticks automatically switch between 4way and 8way depending on what the game you select requires.  Pacman with a 8way joystick is a pain. 

I've since done a few upgrades, the main one is a big lighty-up trackball inbetween the 2 joysticks.  I would have taken a newer photo, but the washing is currently in front of it and I just thought of it and i'm sitting down so....
