I have a Lenovo Ideapad y700 17isk with 256gb of ssd storage, 8gb of ddr4 ram, a gtx 960M graphics card, and an Intel core i7 2.6Ghz. I want to sell it to make my own custom-built desktop. How much do you think I can sell it for and where would be the best place to sell it. It is in perfect condition and it works perfectly with no issues.
