This is still very much a wip.
Cut some 12mm ply and made a horizontal monitor mount.
Fitted a 17" touchscreen industrial monitor I had lying around (It's got VGA, DP & HDMI ports + controls are on a panel connected by a 1.5M network cable).
Mounted an Intel I5 nuc under the control panel with a 1.92Tb ssd and 1Tb batocera image from arcadepunks.
I've got to get power, speakers and controls sorted + tweaking the pc config so it can startup & shutdown without the power button being accessible.
Cosmetics wise, painting bezel and replacement panel black and adding lexan covers, rest of cab was in pretty good shape considering what I paid for it.
So far so good batocera boots and runs OK, dunno if sound works as no speakers connected.
I might cheat with the controls and just have 2 x USB ports so I can plug a PS-Dualshock controller in rather than pissing around drilling 10+ holes to mount some Happ buttons and Suzo 500 stick (for a 1L6B panel).
Grandkids already love it and are hassling me to get it working so they can play Bomberman and Boulderdash.
