Similar situation here; I try not to unplug mine :)
That being said the heat output is so low my mini lives in a drawer and serves to host time machine, a Jupiter notebook server, media server and a couple parallels VMs.
The fact that it just as easily serves up a display on my tv, iPad, Chromebook etc is extremely nice. It's been reliable enough to act like an appliance & fast enough that I never worry what else is running.
