I have a Mini-ITX build, where the mobo only has one PCIe slot, but the case has two PCI brackets. I need to use the PCIe for extra SATA ports, but I would like one or more extra ethernet ports too. The mobo does have internal USB3 onboard connectors and there are USB-Ethernet adapters, but I haven't found any internal ones.
So to be clear, what I would like, is a PCI bracket with 1-4 GbE ports, that connects directly to internal USB connector. Does this exist?
