Over the weekend I spent some time removing ChromeOS from an Acer C720 and replacing it with Fedora 20. Although I still need to add a few more tweaks to the setup I have ended up with absolute bargain. I purchased the C720 as a refurbished model, this was to save a few pounds and to get a 32GB SSD rather than the 16GB version available from the Google Play store. The Fedora install and handful of applications I needed only take up around 5GB of space leaving plenty to work with. Battery life is excellent. General desktop usage easily manages 6-8 hours, streaming video/using the wifi would appear to reduce this somewhat. So for £165 inc delivery (plus a weekend of setup time) I can say I am very happy with my purchase.
