Guy guts TV with a most likely good tube to put in emulation with a flat screen for games designed to be played on tube. One less tube in the world now.
Yes, 'cause playing these games on a B&W tube is totally genuine to the old-school gaming experience.
My first TV when I was a kid was a Zenith B&W 14 inch that I hooked up my 2600 to, and even back then it sucked not having color.
Your complaint should be more towards using a Pi for this. With the space inside that case he could have easily fit a mini-itx PC and have a better emulation experience than the Pi.
