Unpacked and hooked upto keyboard, mouse, monitor and power. Started and just beeped.  Found memory just floating around case.  Reset memory 8nto slots and verified other connections.  Restarted. It started but locked to some school district. After several attempts finally got working.  Provided instructions did no help or correlate to issues with getting up and running. No easy access to seller to receive support.  Only long wait for Amazon or to contact manufacturer which has no support for off lease units.
