I opened up my PC case today and a while later found I had difficulty in putting the cover on afterwards. I then discovered a little metal projection on the edge of the case where the cover meets it that looked bent back on itself. The thing is, I've seen this projection before: it looks like a semicircular disc with a hole in the middle, and it is on the edge of the case.
The thing is, since it was apparently damaged, I had no choice but to bend it out of the way so I could close the cover on the case, but I am wondering what it does, what its purpose is? If I can find a close-up picture of it, I will post it.
