Does the Quad Core iMac have a different motherboard from the Core 2 Duo?
Uses a different socket. Assuming it uses a different board.
I would imagine that it does. After all, the i5 and i7 processors move away from the standard LGA775 socket that the Core 2 Duo used. It also removes the FSB and replaces it exclusively with DMI. Finally, it was released along with the P55 chipset (and all Lynnfield mobos use it), and I assume that's what Apple uses for the quads. I would be VERY surprised if they had the same board.
Yes. Quads uses LGA 1156 while LGA 775. Also, quads have built-in memory controller while C2Ds needs a separate one.
Yes, they both use very different and physically incompatible logicboard architectures. I'm sure the boards could be swapped though, if you're thinking of changing from a C2D to an i5 in a few years.
I wonder if the layout is noticeably different...
Hopefully iFixIt has a tear down soon. I wont be curious enough anytime soon to open mine up though.
Oh I would not bet on that. Getting an iMac board would be very difficult and expensive anyway.
I'd bet that it has a completely different chipset also since Nvidia was unable to get rights to make chipsets compatible with the i5 / i7.
Never seen eBay?
