Good idea. Maybe not only metal but something cool. Subcultural references are nice. Or you can probably create something cool and there are shops where they make a full size vinyl sticker that covers the back of the whole LCD. I have a 12" HP and sometimes I get it, that it's cute and girly.. Even though it's an enterprise series thing not a small commercial mass produced thing. If I had a lenovo x61 or x200t (oh my dream...) then there would be still some who would consider it cute and so. It's because there are people who have no idea what's make the worth of an appliance. Maybe you could consider it to be a filter for ignorant people.
