I am wondering what I should do after I have replaced old hardware in my PC. I will be removing: Gigabyte 78LMT-USB3 motherboard, AMD FX-4170 CPU, AMD Radeon HD 6670 GPU, Ace 550W PSU. What am I supposed to do with all of this stuff? Does anyone have any idea how much all of this second hand stuff will be worth? It is all about one year and a half old. Where should I sell them? I looked on eBay but there doesn't seem to be many other people doing this??
