Back in 2017 i built my first pc, i paid my sisters boyfriend 300$ for the parts, a 680 gtx, i5 2500k, asus z77, 8gb ddr3 1866. The case itself is not pretty at all so i'm thinking about swapping it so i can sell it to some 12 year who has no idea about computers, though the 680 does perform like a 1050ti which is pretty good. So, how much can i sell it for?
