If you can find an Acer c720 i3 it's a superb machine no fan and pretty fast, faster than an old ThinkPad and extremely comfortable to carry! It's still the number one selling Chromebook of all time! I have a 4GB RAM 256 gigabyte 2242 SSD and IPS display in mine! 7 hour battery life (new), 6 hours for most of the design life. Totally trivial to repair!
