Is there a way to tell an RS vs an RSpro via hotlink or other identifier besides the outer case sticker? I see the case height is slightly taller on the pro... but otherwise they are the same?

I ask because I recently purchased another RS, which came in the original box, marked RSpro ... The case looks brand new as if it was recently replaced in comparison to the solder posts which look well used.
I do know you can purchase replacement cases from online retailers rather easily... is it possible to put a RSpro in an RS case (even if you only replace the top half)??

Functionally they are the same. The Pro has an additional layer of FETs to handle the power demands of 5T or lower motors. That's what makes it taller.

The top half of the case is taller for the Pro.
