Question Little scratch MOBO

Excellent picture.

No traces appear broken, so shouldn't present any problems with the system working. You do have some exposed copper traces. If you wanted to be cautious you could take some clear nail polish and wipe that over the damage to prevent it from oxidizing.
 
Ow glad to hear it, we put some clear nail and i wiped the scratch then it disaped, didn't see anymore the scratch but only the copper marks.
 
The long scratch may not be that bad, but there are two small round scratches on the top right near the SMD components. I'm afraid there are broken traces.
 
Up at the top, not even sure those are scratches at all. The motherboard tray is right there, and I don't see how it could be part of either the board or the tray. Dust bunnies?
 
no, once motherboard is works fine, so there is no need to worry about the scratch.. or test the scratch with a multi-meter
 
Those are PCIE lanes, but not 16X. Probably to a slot that may not be used. It probably wouldn't be a problem to find out which slot they lead to and measure them.
