The receiver PCB has been removed from it's case (as has the irman) the smoked plastic front of the keyboard receiver then being glued into a standard 5-1/4 inch case blank, the irman & keyboard PCB's sit behind this "window"
It's going to be difficult to mount both with the tiny hole already in your case, unless i have another/bigger hole made, & a bracket to mount them.
I should imagine other people are going to want their keyboard receiver & irman inside their machine or is just me
how is your keyboard receiver mounted??
P.S why do painted cases look sooo bad under flash photography
