I have the late October 2009 version of the White Polycarbonate MacBook. My MacBook has cracked around the ethernet cable and the USB ports. I was wondering if anyone has tried switching a White Polycarbonate MacBook to an Aluminum MacBook housing. If I was to replace the housing with the Polycarbonate it would probably crack again. If you can give me any input that would be great. Thanks for reading and have a great day!
