I have a 2011 Mac Mini that's been running for about 7 years now. It's running on a DIY Fusion Drive I made by putting an SSD inside and doing some careful Terminal mojo I read about to "fuse" the two into a CoreStorage volume. I used it for graphic design and even some video editing, and it kept up pretty nicely. I only moved on because it had USB 2.0 and that was turning into a bottleneck. So then I gave it to my wife who runs it in a small office. It's stuck on High Sierra (not supported under Mojave), but otherwise it's still chugging along quite nicely.

That is impressive. What are you using it for, some kind of server?

I have a 2006 Mac Pro that has been running 24/7 since the day it was unboxed. It has only had two boot drive replacements and one third party RAM stick died a few years in which I replaced under warranty.
Loaded with the X1900 card and Apple Raid card and 16GB of RAM.
Other than keeping it in a temperature controlled and low dust environment, on a UPS and scheduled cleanings of the insides and fans it's been absolutely rock solid machine.
13 years of constant powered on duty with no failures other than what I mentioned. I think that is pretty amazing.
