hello I am new to pc gaming and yes I do understand that I have a tight budget, but I know there are a few good pcs out there I'm just not sure what to get. I don't expect to run anything to big yet but games I want to get are Dayz, Garry's mod, WOW, rust, etc. mostly steam games. I did find some refurbished pcs on newegg.com but I'm not really sure what I'm looking at. A computer mouse and keyboard aren't needed and neither is a monitor just a nice running pc. I do want to be able to upgrade parts over time in this pc but for now something that will impress me and show me if pc gaming is worth it because I am generally an Xbox one gamer so this is all new to me. And I really appreciate the help!
