Hello! I am wondering if there any affordable PC options (under $500) that my son could play Fortnite on? He does have an xbox but seems to prefer to play with a keyboard. He does have a nice gaming keyboard and headset but no PC. He seems to think he can play on a regular pre-owned laptop but I don't want to get one for it to just break or not be able to be used to play fortnite. Thanks so much.
