I mean only nice inner small box, that is made of galvanized sheet steel
(and provide additional magnetic shielding for rb source, as I think).
It is easily detachable from large outer case and heatsink, and will
not add that much to weight or volume weight. You can put it on
another heatsink pretty easily (but I decided to keep whole casing).

Best regards,
