I haven’t built a PC in a decade or so.
I’m quite happy using a couple [backups are a good thing] of 10 yr-old mini-desktops [some laptop parts] tossed off by the University Hospital @ $10 and upgraded with a SSD.
Maybe I should plan to build a new one in a couple of years. I could use it to develop new drugs to sustain myself...
You sound like me.
I built one every so often.
