The logic board in my iMac 27" 13, 2 (2546) late 2012 needs to be replaced. Will the logic board from the 27" 14,2 (2639) late 2013 match and fit inside the 27" 13,2 late 2012 housing?

I've looked all over and have yet to find a straight answer. Thanks in advance!!!

Thanks Miles Muri for asking that question, we know now that the CPU's can NOT be swapped due to the different sockets. Back to my original question...does anyone know if the logic board from the 27" 14,2 (2639) late 2013 match and fit inside the 27" 13,2 late 2012 housing?

The dimensions seem similar enough, but i've read that it's the placment of the USB, etc ports that don't exactly line up and prevents this from being a perfect fit. Thanks in advance!!!
