Old Pcs or components (DT1 2DN)

Hi everyone, I live in Dorchester and don't have a car. I am looking for any old, slow, or broken desktop computer towers that you are planning to throw away. I am trying to salvage a few older parts to upgrade my current setup. If you have an old PC taking up space in your cupboard or loft, I can walk over and collect it from your doorstep/porch. Thank you so much!
