Just make sure your rough opening that you are mounting the machine in is about 1/4" larger than your machine in each dimension. A good height from the floor to the top of the machine is 53". I am tall, but that puts my eyes about 4" above the center of the playfield, and the shooter knob right at hand on the knee level. A free standing case is nice due to movability, but you have to screw it into the wall or it will tip very easily.
