The assembly process is very simple, only through-hole headers and modules:

There're several options.

First, ME7.8.8 enclosure with 81-pin connector:

It's compact, cheap and can be waterproof sealed. Here's an example of OEM sealant:

Another option is Bosch M7.9.7 enclosure with 121-pin connector:

All these are low-price new enclosures obtained from Taobao.

Also, an old Bosch Motronic enclosure can be used with the same 121-pin connector:

Finally, one can also use a different type of 81-pin connector (also cheap):

It has a simple rectangular shape and is perfect for DIY 3d-printed enclosure! :roll:

Where can I get PCBs (or board files) for this? Or is it not yet functional?

Is the main board meant to be more vehicle-specific, with the modules that plug into it more generic? That is, is the intent to re-use the modules on multiple plug-and-play ECUs?

The intent is to re-use the modules, yes.
The main board is already PnP-compatible with some 121-/81-pin ECUs, but it can be also used with an additional adapter board for other PnP connectors. That's because the main board uses convenient 0.1" header-compatible holes, so the adapter boards can be easily soldered or even press-fitted directly to the main board (in place of the harness connector):

Some PnP adapter boards are already in development.
