Free computer components/computers/monitors from 2013 onwards

[se22cat]

If you have any working pc hardware after an upgrade, I'd really appreciate saving it from the scrap as I can re-purpose parts to make new builds for a variety of projects I'd like to start work on. I can securely wipe storage to ensure no data is left on it, or provide you with the free tools to do so yourself so you have piece of mind no personal data remains. The reason for seeking hardware after 2013 is due to greater power efficiency ratings (very important for stuff that might be left on for long periods of time) and less chances of it failing (vital when giving someone a machine they are using for uni coursework etc). Thanks for reading!
