Beelink T4 for Digital Signage

The Beelink T4 is an entry level Windows 10 device that gives decent performance in an inexpensive package.  Supporting 4GB of RAM and 64GB of storage as well as true 4K and multiple displays.  

This is best for users who want and know Windows 10.

Like all Windows 10 devices this will not be as easy to manage at scale as ChromeOS.  Also you'll need to roll your own remote management capability using traditional windows tools like remote desktop.
