It looks like either of those cases would work. I see some interesting Hammond cases . They even have red front windows available.
I am trying to locate the source of the opportunist cases on ebay. I copied the best case picture and then removed the display and switch from the front and tried a picture match search. So far no luck but I know I have something in a case that has the same top ribs. Will take a look around.
I am going to add a folder to the Files display section and add the SanJ instructions there.
