This motherboard was used in my home lab server. In July it stopped working and was sent in under warranty for RMA. Now, it is having issues. As a bare metal system with Ubuntu installed, absolutely everything works as it should. All USB ports, and PCIe slots have been tested and works. However, when using it to run virtual machines nothing wants to work any more. For that reason it is being sold as is, but working. It has not been tested with Windows though. At this point it is outside of the 90 day warranty to do a RMA claim.
