ATX Motherboard's mounting holes in wrong places?

[Rocko1976]

I have a Gigabyte 970a-ud3 motherboard. It's ATX, yet the holes are not in the standard ATX configuration. You can see from these two pictures what I am talking about. Top is my MB, bottom is Asus. Both ATX. Is this common? Should I drill and install a standoff for the holes that don't have a standoff?

Lower right is missing hole for stand off. Also holes on

Asus board with normal ATX hole pattern.

Ther both different boards. They should both still fit with standard ATX standoffs and should not require any modding.
Have you actually tried your motherboard in a Case that support ATX motherboards.

Yes, different motherboards, both labelled ATX, the holes are different. Look at the right edge of the Asus and the bottom edge of the Gigabyte. Totally different.

ATX specs say where holes are to be, but not how many.
It looks like your motherboard is not a full width, which is ok. There are sufficient holes to mount and keep your motherboard secure.
There are also no holes where they should not be.
One of the pics is rotated 90 degrees which makes it hard to compare.

The hole on the top motherboard, just above and to the left of the F_Panel is odd and out of place. There is no standoff threads on my case which supports all standards-micro, mini, atx, etc.

Is it worth drilling and adding a stand off here since the entire bottom side(looking at pic) is unsupported?

It appears some other Gigabyte motherboards sold as ATX form factor do not follow the standard for the standoff hole locations. Seems like a poor design.
