Im planning on getting my son a gaming PC. I have a budget of about 550 dollars. At the moment it is looking around 520. I was reading online from some "Computer enthusiast" who put a good Entry level gaming PC Build. The only thing i noticed was that there was NO CPU COOLER. Im not gonna let my son do any overclocking, But should i still get one, if so anything in the 20-30 dollar price range? I dont need anything fancy. Thanks!
