That's incredible! I have a professionally built arcade machine, using the original Jamma cab design, using the same proper materials, but which I've modded with a PC inside. That plays most of the games I want to play, and I have add-on trackball and spinner controls I can use with it.
I also have a first revision Arcade 1Up Star Wars machine (the one without the fake coin door), modded with a replacement GRS flight yoke, which I further modified with low actuation force cherry microswitches.
I keep on thinking about getting a garden office built so I can have a proper little home arcade with a Tron machine, something with a built in trackball and a driving game. My wife would be happy to get the two machines out of the house, so it's a double win.
