help me computer experts with networking?

Question

I recently have built myself a new gaming computer.
I download alot of stuff, but I don't want to use the gaming computer's memmory.
So I decide to use the older computer to dowload and use gaming computer for just gaming.
But I want my gaming computer to be able to accese to old computer with huge storage and bunch of data.
I never knew how to network.
Can anyone help me? If I have to do networking to do what I said I want to be able to do, then plz link me some good step by step networking site.
