I am finally building up my pc and I put the motherboard in the case now im confused about something...there are 9 screw holes on the motherboard with metal dots around them which im assuming are for grounding..well my case is the Corsair 300r and it has a metal thing that was already screwed in as part of the case that sticks up threw one of the screw holes on the motherboard. i assumed this was supposed to stay like that maybe to help line everything up....am i suposed to remove this from the case first so i can put a screw in its place? please let me know asap i cant move on till i figure that out...the hole also has the metal dots for grounding which is why i am wondering if a screw goes here..dont wanna not have it grounded right and mess up the MB..thanks
Yes, that is for guiding your board into position during installation. As long as any/all of the other standoff holes are using screws, you will have more than sufficient grounding. It is intended on being left in.
