In the mid-90s, I retired my 486 hardware and brought it over to a local ISP that we were friends with.
It had a second life doing stuff like delivering mail, handling IRC, serving web pages, and whatever else a few of us wanted from it. The performance was fine.
(The Pentium-ish machines stayed on desktop duty where GUIs devoured resources.)
Yeah, I was actually running it on a 386 at first. In those days I didn't have much money and I just dumpster-dived computer hardware that was thrown out behind computer shops. Back before recycling stuff got regulated, PC repair shops threw out totally-working hardware all the time. Every piece of hardware of the web server was free, including the monochrome CRT monitor I had hooked up to it, and the awesome IBM Model M keyboard. The best dumpster find ever was a working Pentium 4 machine, all they took out of it was the HDD! Good times :)
