I thought everyone knew since webwit revealed it months ago?
Unicomp has stock on industrial cases and even industrial mini top parts.
Edit: I think by that time webwit had already disappeared from here and had only revealed it to the Koreans. Oh well, now you know.
I thought everyone knew about industrial mini tops! I don't remember anyone mentioning full sized industrial cases. Anyway, I was able to get both, top and bottom halves from Unicomp.
You might be surprised that they still have industrial M13 cases as well! I know because I got two bottom halves by mistake
They're "compatible" with regular tops provided you break/cut off a small piece of plastic. This would allow you to use the other port-hole for USB or whatever.
