That metal plate will only protect one side of your monitor board. The other side, with all the parts on it, are at the mercy of every conveyor belt and gloved Tom Brady wannabe.
No, wait, I see this one has a second piece of metal on the bottom (the side plate with transistor mounted to it; I think that was Virtua Racing.) So it's Transistor Salad Sandwich with the filling crushed with every drop, plus the neck board on the side being repeatedly stabbed with a sharp corner of the plate.
