Just out of curiosity, how do you distinguish an aluminum cover from a metalized plastic cover? (Plastic, coated with real metal.) I'm not an engineer, but I once worked for a company that had metalized plastic pieces on some of its products. Short of looking at the backside of the parts or scratching their surface, I had a hard time visually distinguishing them from solid aluminum parts. (Such stuff wasn't part of my job, but I was impressed with how good the metalized plastic looked.)

The surface of metalized plastic is electrically conductive, so an electrical meter doesn't distinguish them. And since aluminum isn't magnetic, a magnet wouldn't tell them apart either. The weight would certainly be different, but weighing the individual parts isn't feasible on assembled products. Perhaps rate of temperature change would be a clue?

On the PRS-350, the edges of the front cover piece aren't exposed, so with my limited skills, I can't positively identify the material.
