In my case I have letters that mark the places for the stand offs.Witch letter is for the ATX MB.I have a ASUS sabertooth MB and NXZT Phantom case.
 
Wherever your motherboard has a hole, that's where you put a standoff.

Don't know why your even looking at letters, this is not rocket science.

9 holes = 9 standoffs

6 holes = 6 standoffs

If your stumped on that, I would seriously consider letting someone else build the pc.
