I'm always on the lookout for the beefier chromeboxes, they're pretty small physically and pack a lot of punch for such a little box. Asus chromebox 3/i7 is my favorite so far.
Yes! I picked up a 4GB Acer chromebox with a celeron for $20. This is much better value to me than an RPi because I don't have to worry about ARM. Obviously RPi serves a different use case of tinkering with embedded dev, but tons of people are trying to put docker on these things...
