Cheap desktop for gmod and minecraft?

Ok so I know this is a low budget but I have 256$ To spend to buy a desktop and need help, I'm new to having a computer but I know how to use one. So a desktop 250$ or less and could play gmod and minecraft smoothly would be fantastic if there's such a thing

Literally ANY desktop of that price could play those games, they arent graphically advanced. Ones a mod of a game from 2004, and the other is perfect rectangular polygons

Build your own system, you can buy a upgradekit and install windows.
