My daily desktop is mostly 2012 vintage. This hardware is still in use and works fine.

For what it's worth, that machine is being used while I upgrade my 2001 Computer Of Theseus once more. It's now getting it's third motherboard with CPU - this one salvaged from a 2018 or 2019 gaming machine. It's on its second case, and has seen more hard drive and memory upgrades than I can count - all of them piecemeal. Other than perhaps the motherboard screws and hard drive screws, I'm not sure if anything actually purchased in 2001 still survives in there. Maybe the power cable and pc speaker. And I don't remember ever replacing the rear case fan now that I'm looking at it.

It's triggers broom :-p
