I tend to like more DIY solutions to these. Things like the lowest power server you can get. An article about using such a device to automate as much of your digital life as possible (like automating backups, maybe downloading tv shows, or running a media server backend).
Some of these are kind of broad in scope, but I tend to be interested in storage servers from the standpoint as the backend of your digital life. Which I think for a lot of us keeps expanding. How best to set up these devices, what options there are, and how to make this work easily would be a very interesting topic to have covered well.
