When I came to installing the motherboard I found there were pre-installed standoffs. They sit flush against the back of the case in a hexagon shape.
But on the other side they are round shaped (not hexagonal like the brass ones you install yourself).
I need to remove two of the standoffs so they won't be touching the motherboard. I have tried pushing them out, and using grips to twist them out but they seem to be riveted into the case itself.
Here are some pics to show you.
How can I remove these!
