Another thing to mention, is WOL: Wake on Lan. If you have the ability to plug the Mini into ethernet, you could have it sleep, and then use WOL to wake the mini up when you need it. It would save power for obvious reasons.
I mention this as power consumption at my house is a daily battle. We try to keep all power consumption to a minimum. Even if it sacrifices convenience.
However, I do agree that keeping the mini on all the time is not going to hurt it, unless the environment its in is really hot, like in your garage in the summer time. I mention that, because I have an old Windows laptop out in my garage I use to look things up when I am working on my car, and it died recently because it was too hot. Shut off durning a defrag, and corrupted many files.
Ya, dumb is me. 🙂
