Uh, the player should be metal, the top is aluminum, as-new, and the inside holds more copper then your local bank. Some folks have replaced the top with other materials for acoustic purposes, but this should not be the case with a new player. Maybe someone drop kicked the player, which led it to being "B-stock." Try to exchange it for another player, with the original roof.
How much does your player weight? Should be a little over 30lbs, very solid.
