This is from my old house, so this pic is over 10 years old, but here it is.
I built the cabinet and found a TV with super video input. I have it connected to a power outlet that turns on when it senses another machine turn on. And I have the computer inside (still running Windows 98!!!) run off that plug and set to turn on when a key is pressed. I bought the control panel from SlikStik. So when I press any button on the panel, the computer turns on which triggers the TV to come on. It's magic! I have a shortcut on my desktop to turn off the computer, so I track ball to that, double tap it and the whole thing shuts off. I love it. Just played it with a buddy last weekend while cranking 80s tunes and finishing off a bottle of Jack. Fun times.
