If your device still works, why not sell it? Plenty of websites buy used equipment or offer trade-up programs, including Amazon, Best Buy, BuyMyTronics, eBay, Ecosquid, Gazelle, and Glyde. And of course, there's always Craigslist.
The Gazelle site is typical of many buy-back sites. It helps you calculate what your old gear is worth along with sites such as WorthMonkey. But before recycling or donating your PC, make sure to remove any data from it.
