Overall very happy with the purchase (bought two).  The machines are pretty fast and boot up quickly thanks to Optane..  There's not much software on them, which is good for me as I would uninstall most of it anyway..  These are excellent machines for just basic computing and lower end gaming.  As mentioned in other reviews,  once you open it up you will see there's not much room and everything is butted up near something else.  I went ahead and put another 8 gig stick of ram in and also replaced the on-board graphic chip with a 4gb GTX 1050ti.  I went with the 1050ti so I didn't have to replace the Power Supply.  Normally replacing the PSU  is simple, however this case is pretty tight, so unplugging the PSU cables looked to be a  pain...  It can be done, but it's too much work for me and the 1050ti does that I need it to.  Overall very pleased with the machines and would recommend them.
