I have 6 Raspberry Pis but only 1 at home. I set up some to stream media from my home server and gave them to friends and family. I have a couple at relative's houses for remote monitoring. I have the Pi set up to make a reverse SSH tunnel back to my house. I can then tunnel VNC / RDP and help debug any issues they are having with their own home computers. One Pi is used to wake up my remote file server with a Wake On LAN packet. The Pi idles at under 2W while the file server uses about 80W when on. I run my backups and then put the file server back to sleep.
