In the computer industry their are many parts, pieces and boards, cases, monitors and all the many hundreds of internal parts that go into networking electronics to generate a computers function. People think of a computer usually as a single part of plug and play parts like a hard drive but realistically speaking a single computer set can contain thousands of parts inside it. The good news however is that most of them are recyclable, and can be turned into computer recycling services. Instead of throwing out old computers you should do the planet and yourself a favor and recycle them. You will see the prices of computers come down because of it.
