I'm thinking about building a pc computer but I don't know what parts I would need. I want to build a really good gaming computer because my friend wants me to play computer games with him.
Well all parts in a computer are necessary, You'll need PSU (Power Supply Unit) , CPU (Processor), Ram, Hard Drive, GPU (Graphics Card), Case, Motherboard..
They are all the parts that will go inside the case and plug into the motherboard, Then you'll need a keyboard and mouse (you can use your old ones), Monitor ( can also use old one).
