1. Upgrade my own stuff and servers.
2. Have spare parts to fix my stuff or quick fixes for friends.
3. If I can repair it and do not need it, I found some groups that take them for refugees and needy folks or they go by word of mouth to friends in need. I fix them in a very lazy fashion.
4. I live pretty close to one of the local recycling spots, so I can quickly and safely dispose of stuff I cannot use.
5. eBay is great.

I have gotten a ton of free storage this way, makes it totally worth it. If they give me a few old laptops, I put all their data on one drive and take the rest.
