This is my second Optiplex Micro for home.  We run a dozen of these at work and they have been flawless.  This shipped with wireless on board and external antenna which is different than the pictures that only show a punchout for antenna.  Plan some time to run Windows 10 Pro updates.  Dell SupportAssist is a great tool for maintaining these.  Needless to say, I am a big fan of Dell and these desktops.
