The flipside of this story is: if you're buying a new machine, get rid of the old one! The sooner the better, both for you (if you can get some money for it) and for the environment (the newer your machine is when you get rid of it, the more likely it is to prevent someone else from buying a new one).
The amount of time it takes to dissemble, photograph, describe, list on a site or two, answer email or sms questions, package, and finally ship spare PC components.
