Frameless monitor gives it away. Reading through flyers verifies my original gut instinct.
It is an Artic/ATW chinese bootleg cabinet. Probably originally held Scramble, Mars, Max Magic, or Galaxian.
Artic had 20 different cabinet designs available and like 20 different games as well (bootlegs mostly), and pretty much every game was available in every cabinet (often with unique artwork schemes), making hundreds of different combinations. The actual number of game titles available just keeps growing as more paperwork and more bootleg artic cabs keep surfacing, the number of cabinet designs is 20, and all the various models are listed on a flyer.
That cabinet design is visible on the flyer for New Sinbad 7, albeit not with that artwork on it.
Also notice how the front artwork panel is simply a sideart panel cut to fit.
I have found that MOST "mystery cabs" that people have trouble identifying are Artic brand cabinets.
