Hello, thank you for the answer!

Now, I found the gap on photos, and the "notorious" spacer mentioned.
It is only in the last progress report though.

A compatibility thing that came to my mind is that some N900 accessories like car adapters
make use of the ~0,5mm gap between the back and front case part (they have
hooks that slide into that space to hold the back case when inserting the phone).

If the spacer frame comes with a similar gutter/keyway/furrow/slot? (German: Nut)
these accessories could probably continue to function (with a new usb connector).

Ok, so are there some other nice ideas that the spacer frame layer could allow?

Is there some room left for
* Slots to insert SD-Card or SIM-Card without opening the case?
* display connector?
* second USB?
