On mine the stamped 'dimples' are located on *The Standard* ATX hole
pattern and if a motherboard did not have matching holes in those locations
it would NOT be in compliance with ATX.
In addition there are 3, 'on the flat' (as you expect them all to be),
threaded standoff mounting holes for (the PCI edge of) mATX (and whatever).
I do note that I have cases using all 'on the flat' screw in standoffs that
have more holes than this one. What those 'extra' holes are for I don't
know, for sure (perhaps AT, Baby AT, or some variation), but they are not
part of the standard ATX hole pattern.
One could say that when this case says it's an "ATX Case" it means it, and
doesn't have a bevy of 'extra' holes for whatever those 'extra' holes would
be for; nor could you mount something not in compliance with the ATX hole
pattern.
It's possible that you had a motherboard with 'extra' holes, in case it was
going to be put in 'one of those' kind of (non ATX) cases, and your case
tray had 'extra' mounting holes, in case you wanted to mount 'one of those'
kind of (non ATX) motherboards that use them, so that the combination of
the two having the 'extra' hole (for compatibility with 'one of those'
whatevers) led you to use them; and then the next motherboard had only the
standard ATX hole pattern, which would necessitate removing the 'extra'
standoffs.

It won't align with anything (like the rear I/O plate) if you raise it
another 1/4 inch with standoffs screwed into the already 1/4 inch high
'dimples'.
