Replace A1286 Mid 2009 Logic board with a mid 2010 one?
I've looked deep into this over the course of the past 2 months, and I've came to the conclusion that all of the connectors and components between the Mid 2009 C2D logic board and the Mid 2010 Core i7-620m logic boards are identical, except for the heat sink, bluetooth and wifi board, and isight/antenna cables. All of the screw holes line up (they are both a1286 model number) and both use a nvidia chipset, so it seems the screen would work correctly without any modifications or additional parts.
I'm just wondering, what would the killer be when buying a mid 2010 logic board (with a core i7), a new isight/antenna cable, and a new bluetooth/wifi board and upgrading my computer this way rather than buying a newer macbook pro.
The top case is a bit different as well. The are screw holes for the subwoofer on the 2010 which the earlier model lacks, and the bluetooth antennae on the 2010 has a piece of metal that looks like it attaches to the frame (glued?). The older model has a thin black plastic material covering that area (which appears to be cut away on the newer one, but I couldn't find any info on removing it and didn't want to mess it up so I left it in place.
