The only reason for a 3-star review is because of the ease at which Amazon's return process is, and the courtesy from the call center representative at Skytech. Unable to use product out of box. Received desktop in inoperable condition. Connectors in the back for mouse, keyboard, network connector, usb ports, and hdmi ports not aligned properly and would be unable to plug-in devices and cables.  UnforPoor craftsmanship in your refurbish process. I would be unlikely to purchase from this vendor again.
