[Yeo Kheng Meng] had a question: what is the oldest x86 processor that is still supported by a modern Linux kernel? Furthermore, is it actually possible to use modern software with this processor? It's a question that surely involves experimentation, staring into the bluescreen abyss of BIOS configurations, and compiling your own kernel. Considering Linux dropped support for the 386 in 2012, the obvious answer is a 486. This supposition was tested, and the results are fantastic. You can, indeed, install a modern Linux on an ancient desktop.

This was something I did around 2004 (Gentoo on i486), most things weren't really problematic at that time... but don't build libreoffice or something like that. Also take into consideration that some newer software takes large chunks of memory to build (which is normally not available on i486).
