Scavenging Old Electronics

I rarely buy parts for the project's, I prefer  useing  the old PCB boards as a source of parts.My favorite source of parts are:PC power supply,  devices are placed in a metal container, old RC cars and etc.Many parts are damaged in the process of removing them, so you need to be careful.
Pc power supply can give you nice amount of electronic parts, the metal contanier which can be used as a project box, fan and cabels.
I've saved a lot of money by scavenging old electronics that I bought on flea market.
