My mom's NUC has never caused any trouble running the latest Ubuntu. Network printer, scanner, wireless mouse, webcam, bluetooth headphones, USB hard drives, sleep/hibernation... not a single problem.
Actually the Gigabyte Brix variant because I didn't want to buy the WiFi/bluetooth card separately. But it's the exact same mainboard.
ChromiumOS is perfect for it. It's distributed by Neverware as CloudReady OS.
