Power cycling (more specifically thermal cycling) is harder on the hardware than simply leaving it on. In my 35+ years in electronics, generally if a piece of equipment is going to die, it's going to do so during power up or a really big swing in temperatures (such as the loss of aircon in a data center). I will say this observation is completely empirical and I can't back it up with hard numbers, but it is my experience.
This is why an incandescent lightbulb is much more likely to fail when you turn it on than at any other time. I've read stories about bulbs that have been working for decades because they've never been turned off. I have two reasons for leaving my desktop on 24/7: first, because Linux is designed to be run that way[1] and that allows me to use my uptime[2] as an example of how stable Linux is and second, I have BOINC installed and even when I'm away at a convention, or house sitting, it's doing useful work.
