We're using this as a media center PC (streaming and DVR). The PC came with Windows 10 Pro, clean installation. We did a clean Windows 11 Pro upgrade. Earlier versions of this particular model are not upgradeable to Windows 11. The power supply is lower wattage (perfect for us, but not great if you're gaming and adding high power discrete graphics). The dvd tray, auto open mechanism, was broken. The vendor responded immediately with a replacement. The vendor supplied two USB adapters: (1) Display Port to HDMI and (2) WiFi.  This unit, with a small power supply cooling fan and a CPU cooling fan, is extremely quiet with good airflow. There are a couple of small wear related cosmetic imperfections which, as advertised, are only visible upon very close examination. Price / value, quality and customer service equal 5 stars happy. This HP model is a pleasure to work on.
