Pros...1.  Everything was as described and tower looks like new.2.  Arrived early and was well packaged.3.  Great mini tower to build up with plenty of open slots/bays.4.  Plug & Play ready, powered up and it was ready to go with the current version of Win 10.5.  USB Keyboard and mouse are new, but generic.Minor Cons...1.  Came with an aftermarket USB WIFI antenna that kept losing the signal from 6' away from modem, hard wired the tower to the modem, end of problem.2.  All 4 ram slots were populated with 2 GB sticks for the total of 8 GB's of PC3 10600 1333 MHz ram.  I was hoping for 2 open slots and PC3 12,800 1600 MHz ram that HP lists for this unit..
