My son (nearly 15) is desperate to sell his gaming laptop to upgrade to a pc which he wants to build himself. We’ve listed it on Fb marketplace but had little interest. Is there a demand for used machines and if so is there a specialist site we can try and sell it on? I paid a fair amount for it nearly 2 years ago but now wondering if it’s worthless as technology moves so fast. Any advice from seasoned gamers would be welcome. Tia
