Hey guys, thanks for the quick responses. I guess a bit of an explanation is in order. I have been a PC Tech for eight years and a Mac tech for four. I have performed many logic board upgrades and repairs on various mac models in the past, including PowerBook G4s. I bought this MacBook Pro on release day two years ago and it has been a great machine. However, I am currently dual majoring in applied mathematics and statistics and computer science, and I therefore need as much speed as I can muster. I would simply sell this computer and buy a new one, but it will actually be cheaper for me to keep this one because I have already upgraded the hard drive to 250GB, the optical drive to a dual layer SuperDrive, the RAM to 2GB and the wireless to 802.11N (this was all a LOT cheaper than it might sound). As such, I know I would lose money on selling this computer (people don't like to pay for things that have been modified, regardless of the quality of the work). In addition, I am fairly certain I know people who can get me a Core 2 Duo logic board in the under $500 range, which makes it cheaper than selling this for $900-1200 and tossing in the extra money necessary to buy a Core 2 Duo. I know the casing itself hasn't been modified between revisions, and the shape of the logic board is also the same (the upgrades to FW800 and SR were pin-compatible chip replacements IIRC) except that there is now a FW800 port on the MBP, meaning I would also need to replace the bottom casing. Therefore, I guess my real question was whether people know if the screen from the originals (non-LED backlight) was compatible with the logic board from the newer revisions, (I just need to write code on it, I don't care about the brightness, etc...) and also if anyone knew for sure that all of the miscellaneous connectors (trackpad, speakers etc) were the same between revisions (I'm pretty sure they are, but I want to know for certain before spending $500). The real issue that prompted this is the CD MBPs inability to address more than 2GB of RAM, which is simply too low of a RAM ceiling for me to do my work efficiently. My goal is to upgrade this machine so that it's in the 2.4GHz Santa Rosa Platform with 4GB RAM range for around $500-$600. If I can do this, it should be able to happily last me for several more years.
