I heard that people can get their white macbook cases replaced if they get cracked and stuff like that but what about scratches? I'm not talking about the light ones on the glossy top but i got black markings in the inside top casing (and some on the bottom) around the screen. This is from the insides rubbing together when i carry the laptop with me. This is the June 09 macbook and not the new one so it doesn't magnetically just shut. There is no way to avoid these black markings on the inside casing, can i make a case to Apple to replace the casing?
