Scrapping a computer. Could use some help.

Ok so Ive had an old computer tower sitting in the basement for a while that I decided to break down. This is my first computer bare with me.

Ive broken the computer down to its main parts:

Motherboard
CPU
Heatsink
Power supply
Hard drive
Wiring
RAM

Now do I hand these in just like this or do any of the parts need to be broken down more?

Thx for any help in advance.
