Hello all, I have recently bought my first pachinko machine, a Godzilla, and finally got my cabinet to put it in. Now, it seems mounting the machine to the cabinet with screws seems the safest way of keeping it in there once it's on the wall, but while the cabinet has pre-drilled holes on each side that I presume are for mounting the machine, the machine has nothing? Am I actually driving the screws into the metal frame of the machine to fix it in place? Or am I missing something obvious? Or is there another, easier way? I'm not going to be swapping this out of the cabinet, so it doesn't need to be easily removable. Thanks!
