Bought 2 of these, couldn't be happier.  I'd rate myself an Advanced Novice when it comes to computers, so I was a bit concerned about the set-up process on a renewed unit. (my nightmare was a blinking DOS prompt staring back at me).  Not at all - could not have been easier.  A couple clicks, a bit of info, log into the home network and voila'.  Whisper quiet, super fast boot-up (thanks to the solid state drive), and for my office-type needs - it's speedy.  The unit has sufficient specs to be viable for at least 4-5 years (general office-type use).  I was surprised it shipped with a 'Tenda' mini USB wireless adapter to help in the set up process. Nice touch. It's a simple 2.4GHz, N-150 Mbit, so you'll likely want something better for long term, but it's sufficient to get you up and running.  The system software (Windows 10 Pro)  reached out and updated itself with no effort on my part. As others have noted - no HDMI port, so make a note in case you need to invest a couple bucks in a new monitor cable. (VGA or Display Port). The keyboard and mouse aren't as bad as everyone notes - they're not wireless, but they're perfectly functional. Time will tell re reliability, but I'm a super happy camper at the moment.3/30/21 - Addendum - the keyboard and mouse are indeed c-ap.  A couple weeks in and both have failed.  So... if you aren't keeping your old one(s), invest a few dollars a new combo when purchasing this system.The system itself is still purring like a (fast) kitten - outstanding value.
