It would be 21" screen, and it essentially have ALL the games. I DO NOT build new cabinets from scratch, so it would be a NORMAL arcade cabinet, normal sized, not giant like the one you have. And no, it won't come apart, but you would be able to take the monitor out, which makes for easy moving.
Although if you don't have a way to come here then it probably isn't going to happen, as I DO have a truck, but it is over 20 years old, and is barely putting along, and I am not risking a long trip in it.
