Yes the chassis are different, but I don't think the D250 can cool any better than the D200. Maybe the D250 has a little bit more mass but defenitely less contactarea of this blue compound as you can see in the pictures. There is no contact within the D250 (window) where the D200 Digitalboard has contact to the top of its chassis.
And why do they get the D250 painted black on the inner surface anyway? See pics.
The D200 has a large contactarea (blue compound) in the middle of the chassis where the D250 has this window with this strange "bone" underneath that has no technical function to me. See the pic. This "bone" is just a "plastic-thing" with no contact/wires whatsover constructed. It is screwed to the cover of the digital board, but what's its function? No antenne as you might assume when seeing the drawing on top of this "bone". In the picture you see the back of it.

"Oh, you can buy the other. But then it is a cost intensive learning process"
