As the title says, how different or similar are those two models of Macbook? I could get a cheap and working, albeit pretty hammered Macbook Unibody White 2010, so I'm thinking if it would be possible to transplant its internals (logic board et al.) into a Macbook Unibody White 2009. The mean reason for this is that the 2010 supports 16GB of RAM, as opposed to just 8GB on the 2009 model. Any advice?
