Hello ! I'm kind of new to all this custom PC stuff but i'm a junior in highschool at the moment and i plan to go to college for IT/Computer Science so i think that knowing the insides of a PC will help me in college. If anyone could give me some topics to look up, things to research etc... it would be very, very much appreciated ! btw my mom gave me a PC thats a few years old, so as I learn new things i'm going to slowly upgrade this old PC. And my main goal is to build my own custom PC by the end of summer. Anything helps!
