DOSBox is just far too good to make setting up an old computer worthwhile, in my opinion. I'm all for playing on real hardware, but we're talking about emulating a computer on a computer. DOSBox does it so well, and you don't have to worry about drivers or config.sys. I don't miss those days at all. I run D-Fend Reloaded as a front end to make configuration so much easier.

Why would anyone not use DOSBox?
