I am using this little computer 24/7 as an amateur radio Echolink station.  It is saving me about $20 on my electric bill compared to the laptop I was using for the same task.  The first unit that was sent to me did not work but it was super simple to get it replaced.  The second computer has been running 24/7 since August 2022.  I'd buy again.  It included the OS too.
