Seller was extremely fast to get back to me with a question, so customer service is A+.  I'm using this fanless PC to run a portable astrophotography rig that needed multiple USB inputs that would be exposed to the elements outdoors at night.  I didn't want a fan that could suck in dust and pollen, or cause any unwanted vibration sense I'm mounting this on a deck below the tripod.  The WIN 10 Pro allows me to use Remote Desktop and remote Wifi into the unit so I'm not limited by running cables.  And if I need to ever control any external devices having the old-school option of RS-232 ports opens up so many possibilities.  Solid little PC for science or lab applications!
