Other then the Cutout connector which is not used they do look identical. You could use either board because the hardware seems the same. What might be different is the firmware version. But even with the older firmware the cooling fan was controllable when plugged into the 2nd from right plug. I've included a pic of my board with that plug circled in red. I had to actually add the green plug to my board as it was the one missing.
On my CTC which has the same board it had the green plug but was missing the little chip in front of the plug. I have since added that chip to it so it has a cooling fan now to.
