(Kind of) Budget Linux Gaming PC

Hey, all! I'm trying to build a fairly cheap Linux gaming PC, but I wanted to double check my parts list before I buy anything. If anyone could let me know if I'm overpaying, or if there are better options for the same (or even a lower) price, it'd be greatly appreciated. Thanks!
