[SOLVED] Sorry if this is the wrong forum but can anyone tell me what this is? I heard something rattling in my case and found this at the bottom.

Solution
What kind of case do you have?

The only thing that it reminds me of is some fans I used once that had a rubber and plastic center and we would push a plastic pin like that through to lock the fan in place instead of using screws.

The other thing I can think of is possibly a part of the case that was never put on properly.
