I was given a 1st gen white Macbook when they first came out. Since then I've replaced the HDD, NIC, and a cracked topcase, which is now cracked again - I'm careful with it, but strong magnets + plastic + time = crack. It's not my primary computer, but it's still nice to bring to school with me. So my question is, does anyone make an aluminum replacement case and topcase for the plastic macbook? Only the topcase is damaged but after however many years with the same laptop I'd like a change (not a huge fan of plastic in the first place). I've been searching for a while but haven't found anything.
