/diy/ - Do It Yourself

It takes very little effort to remove the steel casing from a PSU, as it's typically only screws holding components to it; maybe the occasional zip-tie inside.

You can clip the wires easily to take those in for recycling as well.

If you want to go a little further, it takes a touch more effort (sometimes you have to pull things off the board to reach the screws in this case), you can unscrew components from the aluminum heatsinks and pull those off as well.

Take the rest to an E-Waste drop off or see if someone will take them for cash as well; depends on what's available in your area.
