If they say "Die-Cast" almost certainly either aluminum if you are lucky, or more likely 'pot-metal' - neither is particularly robust, arguably better than plastic, depending on what sort of abuse it is given...
Often they put a very heavy enamel or powder coat on die-cast bits, which can also have a very smooth finish, so the result ends up looking like plastic. I'd suspect that Ringuy is right in that you have a metal frame w/ plastic top and bottom panels, especially on the top as that is easier to make work with the LCD display and other switches etc...
