Unless my old eyes and scratched bin's are decieving me, the pretty picture of the blue box has only 2 visible screws holding the top on at the front....even assuming a repeat on all four sides, that's 8 fasteners.
The fasteners on the blue box have not changed much if at all. But the fire box which now contains the blue box has something like 30 or more screws all around the mounting flange of the removable front cover plate. That is the one which will take some maintenance time.
You should be able to see pictures of that box, but with a transparent display cover instead of the actual SS cover plate earlier in the thread.
