I found this unit within my old computer parts. It has audio inputs and USB ports. After running a check on Google images, apparently this item is a Dell OEM Control panel board for DELL Models Optiplex 790, 990 USFF and Poweredge T340 with Audio and USB ports. As I have absolutely no way of testing this, and no other identifiers apart from what Google has told me, it is being sold as For parts or not working. The unit looks in Brand new condition. Please look at images
