Will a Mini-ITX board fit under an mATX case?

Question

Frame

It's just that mATX cases are cheaper than

Mini-ITX, which cases will the board fit into? (except Mini-ITX)

Answer 1

easily. in terms of size, definitely.
question: are there any seats in the body for a mini.
usually there is. but not always.

Answer 2

I somehow specifically looked at a bunch of cases, there are holes for screws for miniitx boards everywhere (they coincide with the standard ones for larger boards), I assembled at least five very motley machines on very different motherboards of this form factor, everything fit perfectly
ps mitx board looks very funny in an atx case, a huge empty box with a power supply is larger than the motherboard.
