It's x86; it works better for hardware accelerated video playback via VAAPI due to FOSS Intel drivers; because it's fully integrated out of the box, its total cost is a bit cheaper than an RPi, and as a single unit with no assembly, it's quite a bit faster to deploy.

I'm using these: https://www.amazon.com/MeLE-Fanless-Computer-Ethernet-PCG02/.... Works great with Linux, and has a very customizable BIOS.

Neat. How to get without Windows?

Haven't seen it available without preinstalled Windows, but even with that, the price is good, and it's easy enough to wipe it and install Linux.

Thanks. Shame to see MS get even a penny of my money however.
