As of right now, I'm selling computers off Ebay. I build custom P.Cs and I found someone making computers with an option on the bottom of the screen that allowed the buyer to build the P.C him / her self. They got to choose what they wanted on their new computer. For example : John the buyer clicks on a button that allows him to add a different graphics card to the build. Does anybody know how to do this and if so, please help!
