Great little unit. Lots of power.  Initially planned to stick 16or 32GB of RAM straight away... but after 6 weeks of use... I'm kinda happy with the 8GB.  The Optane helps greatly I'm sure.  Will need to increase RAM when I start adding VM's but for just one instance of Windows the 8GB is more than fine...even using Chrome as browser.  Hardware is great.  Small. Solidly built.  Well laid out.  So compact and tiny.  This is my first home Windows machine in 10+ years, replacing an old 27" iMac and loving it all so far..  on 32" inch screen.
