Oops. Wrong way, pin 1 of cpu is seen at lower left of the lower picture of your post, also ide pin 1 can be seen.
I have thought about putting colorful epoxy dots on the pcbs to mark pin 1:s.
Also, maybe laser print pcb "silk screen" on stickers and attach them on pcb.

I dont know for sure if the metal shield will fit once you place the board other way around. Possibly the metal shield will need to be put aside.
