The white injection molded case I have is the same one shown in the video link I posted about the new enclosure. At 25 seconds you can (not a good view but it is visible) the area where the 3 push button holes are. That’s where the ethernet jack is located for OSPi.
Here’s is a picture of a case like mine. Note it doesn’t have the OSPi board in the picture.

My real issue is not that the old case needs modification to work – I knew that.
I was more interested in the stand off info. And a drawing with the locations of the other connector cutouts would be great if anyone has that.
