I know this is a month old, but this was randomly recommended to me in YouTube and I watched their "ad", even though it's free to install on a Pi or any other device that can run Debian or Ubuntu.
It works well in a Pi, but their documentation is out of date, and accessing the web GUI isn't as easy as it should be, especially for new users of Linux. There's no way to (officially) set a static IP in the OS. I searched their forums, and followed their guide, which didn't apply anymore since they're using NetworkManager now. I applied a static IP via that...and FUBAR'd the webUI. A simple reflash of the uSD card doesn't work either since there are hidden partitions or something because the settings still persisted after two DDs. I had to zero out the first few megs and reflash it in order to get it to work again.
That being said. I'm going to give it to a friend as a no hassle/small footprint/low power piracy box and Plex server.
