These have been mentioned here before, but this is the cheapest I have ever seen these.

I can't figure out how to install Ubuntu Server directly onto the eMMC storage, but I installed it tothe USB 3.0 port on a flash drive, and it works great. Ubuntu desktop, Linux Mint, and Windows 10 all work decently well.
