Another part that might be different (if it's not a date) is.
My board has:
H. 06. 04. 06
The other board has:
H. 05. 11. 05
It's located in the RY2 spot.
And one other part looks different.
My board has a blue, flat, rectangle part:
47n J 63OV
The other board has a green, rounded, thin, rectangle, rubber coated part. I can't see the number on it in the picture.
The parts look like they are fitted in the CM3 section, but it might be the R3 section. It's hard to tell.
Other than those differences, the boards look identical from what I can see so far.
