Well, when it comes to wear and tear on components I am a strong proponent of leaving the computer always on. Most of the wear on things like fans, disk drives, etc., come from spinning them up repeatedly. They last "almost forever" when perpetually on in my experience (at least if there's the occasional necessary vacuuming of the intake and output grates for the fans and the heatsink on the motherboard are done). I never sleep my laptops when they're not on battery power for this very reason.
I always kill the monitor when I'm not going to be using it for an extended period, though. Those are the power hogs, particularly on mobile hardware.
How about the CPU and PSU? Will they die sooner if electricity is constantly flowing through them?
Given that I have a desktop that has run almost continuously for a decade and laptops for at least 7 years, I say no. I still have one of my earliest laptops that runs WinXP that's going like a top, though it's not been in "constant on" mode for 5 years now since it's very rarely needed.
I have never had a CPU die, ever. I think I've replaced the power supply in two towers and both of those "died young" and I have to believe they were defective. It was a "just outside of warranty" death situation.
I've seen way more mechanical component failure, particularly fans, than I have seen electronic component failure. Laptop keyboards also seem to get wonky with very advanced age on a routine basis.

. . . the presumption of innocence, while essential in the legal realm, does not mean the elimination of common sense outside it. The willing suspension of disbelief has its limits, or should.
