I've puttied holes and blemishes in the cabinet and then finally I sanded all parts manually and primed them with diluted black wood color. Now the box looks more like a video game machine. In the next few days it will again be sanded and painted, probably a total of two times. Also, my dad and I fiddled with the plexiglass until bezel and control panel finally fixed appropriately. The holes for buttons and joysticks are drilled in plexiglass and the wooden control panel. After painting everything is then assembled for the first time.
