Yep, I built my PC in 2018 as well.

Thanks to the incredible life of the AM4 socket, I managed to upgrade CPUs 3 years ago, and upgraded my GPU 2 years ago.

Between AAA gaming becoming garbage, and the AInflation of components and artificial scarcity, I probably wont upgrade/build new again for at least 5-7 years short of catastrophic failure. . . assuming I am even allowed to by that point, with how they are seemingly trying to push consumers out of the market.
