The last step was how to put everything in the body.
This was my floor plan.
- move the keyboard controller board to 7 o'clock direction, to accommodate custom USB-C cable connector and USB power bank
- put USB power bank aside the keyboard control board
- put Raspberry Pi on the keyboard controller board
- install switch and USB charger connector to top right corner
First any conflicting bosses, pillars and supports were removed, to make sure the floor plan works.
Looking into the keyboard controller, all FFC & cables have marginal length, except touch controller FPC.
The FPC is 0.5mm pitch 6 contact.
I installed the FPC extension and long FFC.
New bosses were installed to hold the keyboard controller board.
Holes were punched and drilled to install switch and USB connector for charger.
Bosses were attached to Raspberry Pi board too.
This is finally assembly.
Power is distributed as below.

Oh BTW - the enclosure screws are tricky, they are hex cap screws (some are trox but open-able by hex), you may need some special tool like this.
I replaced them with regular Phillips screws after all, they are M2, short ones are 4mm, long ones are 8mm.
