It's refurbished, what do ya expect? It runs. I slapped an SATA HDD in the included tray and fired up a Windows 10 Pro install off an HP OEM CD. Worked like a charm. This machine operates desktop quiet.This particular machine is destined to be a modest server built for a small office running Windows Server, MSSQL and whatever else the office needs.Pleased with the purchase, might buy one to run some virtual machines in my home lab.
