Answer to: Do i need a new upper case?I have been researching this housing for our school district and found that Apple is the place to go for me. If it is the "chip", "cracked", "dirty,filthy hand rests" - the part#922-7754 is the replacement, Version2. This one is for the macbooks that were Early/Late 2006. You can get one of the original housings except that it will continue to crack, get dirty, etc... Version 2 is the better housing for your macbook. Because I work for the schools we get an education price. I guess googling 922-7754 or eBay you may find something in your price range. I would buy from iFixit except they do not carry the quantity I need (50+). I would however use their guide to install. Very good for old girls like me to put computers back together. Good luck!
