> I recently purchased a mini PC with an Intel N5105, 16GB of Ram, 512GB NVME SSD, two gigabit ethernet ports, two HDMI ports, many USB ports, and Wifi 6. This system was $180, all in

That's an unusually low price, assuming it's new. Can you give a reference of the shop where you purchased it?

For example, the first price I've found of a Gigabyte Brix (a relatively common mini PC) with an N2807 + 8 GB RAM + 512 GB SSD + no wifi, is 210+ USD.

One of the cheapest x86 systems that I'm aware of, is the Odroid H3 (+), which still costs 129$ without RAM/disk/Wifi.

This is definitely a machine I'd suggest as ARM SBC competitor, but I'm not sure that the price is representative of mini x86 systems (when I was looking for one, a few years ago, it was the cheapest by a significant amount).
