Would it be possible to upgrade the motherboard in a MB063LL/A (May 15 2007 model) to the motherboard of a MB404LL/A (current model)? Basically I want to buy the MB404LL/A motherboard and put it in the MB063LL/A. I want the GMA X3100 Chip and the support for additional RAM, but I really do not want to buy a whole new mackbook. I figured this would be a cheaper way to "upgrade". I am aware that this would void the wareenty (almost up anyway). I have the tools to take apart the macbook I just don't know what a motherboard swap would intail. Thanks.
