It would be interesting to just have a list of what constitutes "complete". It seems like there are a lot of region/channel specific variants, along with changes made during the production of a given model. The two different Mac II ROM variants, the 3 different Plus ROM variants, beige vs. platinum, 512KE's with Plus' PRAM, 128k's with different floppy drives, 128k/512k has 2 ROM variants, LC II's with different ROMs, etc.

Especially as time goes by and people are mixing and matching machines, just determining what was a shipping configuration is getting increasingly difficult.
