Wo-we's AMD A9 miniPC is $79 USD new, has 8GB RAM, a 128GB M.2, and a Win10 license. I've been running one as a geostationary satellite ground station for close to a year now and it's great! It also doesn't have the heating issues that the Raspberry Pi 3+ I replaced it with did. https://www.wo-we.com/collections/mini-pc
