So I ordered an MSI gd65-z87 for my first build, and when I opened the box, I noticed that there was a loose screw rattling around in the antistatic bag. I looked and I can't find out where its from. I don't know if I should return it or not. From what I can tell, there's no scratches or anything on the motherboard, but then again, this is my first build. Should I return it or not?
