If you bid on and purchase the contents of storage containers you are undoubtedly skilled at sorting out what you have and dealing accordingly.
As far as computers and electronics the shops I have worked with in South America have crews disassemble computers and sort out the innards. They separate the steel cases and racks into a gaylord for steel. and the muffin fans into a storage bin for those as well. There are also aluminum heat sinks. All of the things removed can be sold for scrap value while you are slowly progressing towards what you are looking for, circuitry with precious metals. If you were to patiently do this type of sorting at your own pace you will accumulate specific types of e-scrap. Different types of e-scrap require different techniques. You will be able to make better decisions about how to proceed when you quantify what you are collecting and how much of it you have. In the meanwhile, you can sell off the aluminum heat sinks, power cords, batteries, muffin fans, end even working hard drives.
You may have accidentally developed an interest in this but don't accidentally get yourself into a chemical mess by jumping too soon. Be informed, read about different methods here on the forum, and when you are ready, then refine.
