i'm looking at my old HP media center, and at the top of the front plate there's a little raised 'hp' logo in what looks like a on/off button if you didn't know better. it's clearly a separate piece of plastic, something i'd definitely want to remove. it could probably be sanded down to where there's just an outline, or popped out to leave a good little hole.
what would i use to fill the outline? or, as this is probably going to help further down the road, how do you fill larger holes in plastic?
