I am 14 and am from a lower middle class family. I only make money occasionally. I am wanting to build a computer but I only currently have $136. I need help building a computer which costs at most $250. It also has to be able to play Fortnite. Please do not say "it's not possible" because I know it is. I already have a GPU but I would appreciate a better one considering it is a Radeon HD 7470 My current build :http://
