Im looking to build my first PC. I was thinking about a Cyberpower since im only 13 and i dont know if i am ready to build a PC. But i might as well give it a shot. My budget is $500 and a OS needs to be included. Thanks so much in advance.

Good day! I am currently in the process of choosing hardware components for my first PC build. My budget is under 1000 and I have a list of the hardware I have chosen, albeit after many hours and lots of coffee. If you have any suggestions or tricks of the trade I would greatly appreciate them...
