A tower PC, WiFi enabled, with Windows 10 installed. It is a few years old now but is still in reasonable working order. It was bought as a games machine so reasonably high spec at the time. However I have to say that it would freeze when playing 3d games. I tried everything I could think of to sort it to no avail so I’ve been forced to replace it.
Everything has been removed and Windows 10 reinstalled to the extent that it’s waiting for someone to input their Microsoft account to get going. As such I can’t tell you any specs of the machine but hey it’s free. I don’t think it will upgrade to Windows 11 either
