Hi,
Keeping servers running 24/7 does prolong their lifetime. The motherboard and peripherals hardly gain any benefit at all... only the capacitors are susceptible.
However... the hard drive is s different story.
Failure Trends in a Large Disk Drive Population[^]
TL;DR: Hard drives fail faster if they are power cycled.
Many years ago I made a Russian system administrator cry when I rebooted a Linux box that had been up for 4+ years. No, I am not kidding.

When the machine is off there is a chance insects (ants, spiders) may move in,
- when machine is on it's too hot & dry for them.
The support chips on the mobo have such thin legs ants will actually bite through them,
and spiders are actually quite wet (conductive).
Very small chance, but I've seen both happen.

Thanks for the link. I did notice this in the study:
As is common in server-class deployments, the disks
were powered on, spinning, and generally in service for
essentially all of their recorded life.
That makes this study not applicable to the fundamental question.
Thank you for your time

Power on hours versus on/off cycles has been argued for years, especially when it comes to motors (fans, disk drives, etc).
The most important thing to consider is never letting the smoke out. Electronic devicess are powered by smoke. If you ever see the smoke escape, they no longer work.
Arguing with a woman is like reading the Software License Agreement. In the end, you ignore everything and click "I agree".

If they're vintage hardware from 15+ years ago IMO it's a minor miracle that they're still working as is. If it's just apathy that they're still running on museum pieces I'd strongly recommend migrating to new boxes running a modern OS or virtualizing the apps to do the same. 15YO hardware is on borrowed time no matter what you do; new hardware won't care either way and VMs are like: "LOL WUT Hardware?!?"
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

My work PC is never turned off because I need to be able to access it without waiting for someone to have to manually power it on. The monitors turn off automatically soon after I lock my workstation for the day. I always shutdown my home PC at the end of the day. Have never experienced a hardware failure. Yet.

There are valid points made here for both sides, so I'll skip that. I just wanted to let you know that if you DO shutdown stuff, I have written a pretty nice application for doing remote WOL and shutdown. It supports waking up remote servers across the Internet (I do that myself daily). I offer it free and open source to everyone. https://wol.aquilatech.com/

Well thats cool. Have not looked at it but: Thank you.

Lucky you.
I have lost hard drives, Graphics Adapters, Memory Chips (causing BSOD while running).
But the scariest thing I have ever done was cycle a few Novell servers that had been running for years.
Out of about 10 of these old DOS based network servers, 2 never rebooted because of hard drive failures.
Most had errors in their startup files, from changes that were NEVER tested. And MANY had never been properly backed up.
Trying to explain to a business owner the risk of turning off his Server, and explaining that the hardware is rated for 5 years, he has had it for 8 years, and has not rebooted it in 3 years... Your luck might be ready to run out.
I, too, used to turn my big machine off every day. But I now leave me machine running all the time. My monitors are turned off. The machine self-regulates its power consumption. But a BIG part of turning the machine off before was Power+Noise+(The OS would CRASH if left running too long, like 25hrs, LOL)

The best is seeing robocop going down afterwards...
I can't still decide which of both robots is going downstairs more elegantly...

Step 12 is missing! That's the one where Microsoft dismisses the bug as not being reproducable and chucks your bug report in the virtual dustbin!

Not all bugs get closed as "not reproducible". Some get closed because "it's too close to the release of vNext, and we're not fixing any more bugs before that".
Which would be fine, if they fixed the bugs after the release. But they don't. Because the bug report is closed.
So ten versions later, the bug is still present. But if you report it again, it will be too close to the release of vNext+11 for them to consider fixing it.
