Perhaps I have some wires crossed from too much time as a sysadmin, but I take a 5 year old (+) PC (or any machine, really) as a mark of pride, not any bit of shame whatsoever. It speaks to a high degree of reliability which often speaks well of the operator (even if just "choosing robust hardware" is a component of this)

Some stories to add some color to this: Ran a very primitive file sharing server for my university on a dual P(2 or 3, don't quite remember) machine that was probably around a decade old by the time they finally ended up retiring it. My home fileserver is a ~10 TB 4U monster, running on (conveniently) 5 year old hardware and very boring FBSD. Outside of moving apartments, it has not had unplanned downtime once, I will continue using it as long as this is true and would be sad if I didn't get another good few years out of it.

I _WISH_ I could get the same lifetime out of desktop PCs but I tend to find assorted parts failing at an asymptotic rate around 3-5 years. The world in which we all use <5 year old hardware is a sad one, to be avoided, to my eyes. (To clarify, I don't mean this in any luddite sense, I don't believe tech should stop moving forward, but I long for more robust products with longer viable lifespans, such that one can make a choice to upgrade rather than waiting for the inevitable.)
