I just started to build a PC for the first time so I have a question about standoffs. I know theres the brass and plastic ones, but what about standoffs that come as part of the case? (Please see pics) -standard ATX format- I read somewhere that these are the standoffs, but I am concerned that they might make the MB ground. Would covering them in electrical tape or something be a suitable solution? Or Rubber/Paper Washers? Answers and Comments are very much appreciated! Thanks!
