[主機板] 19cm x 17 cm mATX motherboard in a mini ITX case?

Hi

Has any Ching tried installing a 19cm x 17 cm mATX motherboard in a mini ITX case?

This is supposedly doable in a  number of mini ITX cases, but I wonder if the four standoff holes in such 19cm x 17 cm mATX motherboard will correspond exactly to those of a genuine mini ITX case.

Thanks in advance!
