I received the PC yesterday.  It took me 4 hours to set it up.  I am a professional IT with 30 years of working experience.  I have good working experience in Dell Optiplex PC.Pros:It's a solid built PC for office.It comes with 8G RAM and 250G Hard Drive.The VGA port works.  I didn't test the Display Port.It comes with Windows 10 Pro version 1809.The Windows 10 activate key works.Cons:The power cord doesn't work.  Please see the picture.  It's the wrong type of power cord.The keyboard has a missed "leg".  Please see the pictures.  One side has "leg", the other side doesn't have one.The PC has a loosening component.  Please see the picture.  I don't know what it is.I can not install the update, KB4494441, by Windows Update.  This one is a killer.To solve the Windows Update issue, I have to install the latest Windows 10 version 1903.
