I have an HP omen and I want to move it into a new case. I want to replace the graphics card, mother board, and power supply. I was wondering if I bought those new components and kept my hard drive ,ram , and core i5 would it save my Windows info and all my games and files on my pc when it is all switched over to a new case with the new power supply, motherboard , and graphics card. Also would it be hard because I am 16 and never built my own pc.
