Chromebooks make a pretty nice, Linux friendly machine. They're usually cost optimized given the market they address, but that's fine if it fits your needs. Sometimes they have "weird" hardware, keyboard/mouse controllers and stuff at least wasn't always "pc standard", audio controllers seem to be commonly outside mainstream as well.

It's nice to run Linux on a machine that was built to run Linux. No silly windows key, no fighting with firmware that was built for windows first. I have a Chromebox that was a great mini desktop and the pricing was nice. My first Chromebook ran FreeBSD pretty well once it was no longer needed for ChromeOS, etc.

You have to shop carefully, you want something that's easy to put a MrChromebox firmware on and doesn't have any known issues with the OS you want to run. It's been a while since I purchased a ChromeOS device and the current state is different than it was then; I'm not sure how easy it is to find reasonable options now, but there were plenty of good options in the past. You also want to be sure that it has enough ram and storage for you needs or that those are expandable, but I think soldering ram and storage is pretty common across the range.
