This is a small form factor PC, competitor to an Intel NUC or a Lenovo M series Tiny. Comes with OS preinstalled, but also apparently supports Ubuntu or Chrome OS.
The outstanding features are it's newer Apollo Lake chipset, and HDMI 2.0 port which outputs 4k at 60hz, plus you also a spare 2.5" bay for you to stick in a bigger drive if required.
Also quite a few options in the BIOS
It's definitely a lot cheaper than an Intel NUC6CAYH as it already includes storage, RAM and operating system.
