Also I noticed your setup does not have a CPU cooler do some builds not need one or something? And how much do you think you spent on other accessories for your build such as mouse keyboard etc if you even bought any of that
Like Legend said. The CPUs come with fans. Very rare that they don't. I haven't had any issues with the included fan.
Mouse, keyboard, monitor, the optical drive, network card and speakers I already had.
Mouse, Keyboard can be gotten pretty cheap 20-40$.
Monitor is going to be somewhat expensive depending on size/resolution. And you could use your TV.
Optical drive maybe 20$.
Network card, difficult to find, but may be able to find one for 20$.
Speakers, 20$ maybe more for better quality. Less if you know where to look. If you're using your TV, not an issue.
As for the OS, that'll probably be the most expensive thing, barring a new monitor.
Keep in mind those are US prices.
