Unidentified wire
It's a cable designed to link your case's USB Type C port to your motherboard. When your motherboard includes this port (which is rare), you can find it just below the 24 pin ATX/RAM slots. A closer view shows: If your motherboard lacks this feature, you have three options: 1. Purchase a motherboard with the connector 2. Ignore the USB Type C and leave the cable unconnected 3. Use an adapter that converts a USB 3.0 header to a Type C, such as the Silverstone CP14.
Thanks for sharing the details. I understand you're unsure about the link.
