Personally, I would recommend to buy someone’s old gaming pc. I bought mine thru Offer Up from someone that has basically upgraded their system. I paid $400 for it and the person that sold it new what they were doing. It was basically built from old/extra components.
I don’t think I can run some games at max settings for long, but i haven’t had problems playing games. It was stress free and we double checked that it worked before i walked away with it.
If I had to i would totally do it again. Just stay within your price range and make sure it works before you trade the money for it
