Yes, seven years is a really great run... thank you, gentlemen, for your thoughts. I'm aware that the ports wouldn't fit, etc. I'm not looking for something pretty and am OK with punching new holes in the body, etc. for use in a home workbench environment. However, the rest of the system.. the LCD, camera, the new HD I've put in, bluetooth, temp sensors, ambient light sensors, hinge clutch, etc... there is a lot here that works well and, short of recycling the entire thing, I'd like to repurpose the working components to build a system that can be used with Mountain Lion and more modern applications. In order to make this happen, I will fundamentally need to have a new motherboard and processor; but there is obviously no point in getting the latest and greatest to support (for example) a retina display if the LCD is an '06.
So, I'm looking for suggestions on a newer motherboard / processor that I might look to use with this chassis. I'd like it to not kill the bank, but also fit in the body, and use with the rest of the components available. It appears the logic, I/O, and WiFi boards are individual boards, so I can probably just replace the logic board.
Thanks for the discussion.
Paras.
