I have computers that are ~20 years or even more and still work fine. My main computer which I just replaced is ~14 years old (with some components even older than that), was used every single day, and is now a perfectly functioning server. I have stacks of SFFs and minipcs from eBay going back to 2008 but most from 2012-2015, which have been running virtually uninterrupted for a decade, and still working fine. I have several laptops from different OEMs, business and consumer lines, that are as old as 2008 and have been used regularly for at least 10 years, all still fine.

I understand what you're saying but saying it isn't enough. There's nothing to support your claim.
