Learning how to build a PC

To develop my knowledge about what's inside every computer, i have rebuilt it with my brother as he has better knowledge than me about it. We broke down all of the parts of it and step by step he explained what each of the part do and how to put it into the case of PC. I learn't that all of the parts are compatible with each other and without a part, it could get damaged or not work properly. Also in lesson, we learn't how to build a PC as we worked in groups and we had to take photos of each step that we did, so after we could make a presentation how to build a PC and explain it step by step.
