So if they're never obsolete because you can always get a $99 replacement, where should I send my 486 to trade it for a Ryzen 7?

This era reminds me of the time that my grandmother (in same house) got a new Compaq with a CD burner. It was running windows ME. My dumb ass thought that because a had disk drive could be mounted as a volume over the network, a burner could too. Turns out you can sort-of network mount a CD drive but its not usable. The days and hours I wasted on this project, including convincing my mom to take me to Fry's in Burbank to get a Netgear hub (not switch!) to glue everything together.

Ahh I remember that little white desktop

Wow that's certainly a blast from the past. Even had one for a while.

They were ok for the price... I think they were probably the most responsible for squeezing every bit of profitability from independent builders though. It really became a race to the bottom, combined with more interest in mobile/laptop computers.

I remember in the mid to late 90's, you could build a computer for someone and walk away with enough for an upgraded system for yourself. Of course the churn on performance was very real. IIRC, 1992 maxed out with a 486 DX2 @66mhz. Around 2000 we crossed the 1ghz mark from both Intel and AMD. We went from OG Doom that couldn't cut it full screen, to Half Life and Quake 3 Arena on Voodoo 3 and early NVidia cards.

The author mentions Packard-Bell which always just had the whiff of 2 legit companies and was enough to trick uninformed shoppers at Walmart that they were buying high end. Remember in 1999 if you didn't read Computer Shopper the only thing you knew about PCs was what you saw in TV ads.
