Quoted from xsvtoys:
My first thought is hacking that, the price is good. This would be assuming it is a playable form factor with riser. I have been trying to figure out a way to make a full MAME setup somewhat on the cheap. Cabinets kits are expensive, such as $750 here: https://gameroomsolutions.com/shop/32-arcade-cabinet-kit/
If the controls are decent quality it would be good, you would have the control panel all done. Seems doubtful though, they probably are cheap ones which would need to be replaced. If the trackball on the one version is actually a good one that would be a bonus.
You could set this up for both vertical and horizontal games, the monitor is basically square.
It appears to me that the black box on the back of the monitor is its power supply. The ribbon cable connects to the control panel box. I am assuming the mini-PC or whatever it is is inside the control panel. Need to get that control panel ripped open and find out whats in there.
"A friend of mine " runs a raspberry pi with sd card full of arcade games to a tv and x-arcade tankstick. Pi, card and tankstick total was under $200. Such cards cold be found on a popular auction site so I was told. Even came with the frontend.
Beats having only 4 games.
