This unit is a good unit, I have another unit that was from HP that was pre-configured with the Wifi in the unit. This unit DOES NOT HAVE WIFI in it. You will need a separate adapter if you would like to add it on to a wireless network. Overall a good unit. When I asked (I had an issue with one of the RAM units in it) it was not seeded correctly in the unit, thinking that the unit was only a 8GB config. After removing the case (Super easy to do) I popped out the 2 RAM units & re seeded them in the slots then it worked fine. It showed up with 16GB of RAM.  It is 4 stars because I do wish that the post did say that this unit DOES NOT HAVE THE WIFI Module in it.Without the SN of the unit you can not see the Pre-built specs of when HP made this unit.
