Tell me please
How do they fix the inner frame inside the case?

on the back panel I see 4 screws for the outer shell of the case, but I do not understand how it is attached to the front panel?
from the outside there are not any holes and screws

Can there be a threaded connection in a blind hole?

Only these four screws and four screws on the rear panel hold the entire frame?
