I have had one for four years.<p>My Setup:  OpenSUSE (BTRFS with their Snappy is awesome)<p>Two drives that are redundant.<p>CrashPlan for off site backup<p>I also run my IRC (Weechat) on the box and glowing-bear.org as the front end and this is the BEST thing ever. Run my printer from the server and have a personal R-Studio and Juypter Notebook server running on it. I love it.
