I have to disagree. If I saw a PC being thrown away, I probably wouldn't even think twice. But if I saw a Mac, even an old beige one, being thrown away, something inside of me would die.
Heck, I saved an old Power Mac 7500 from being thrown away. Works like a champ.

"Something inside me would die"...if something serious happened. i.e., loved one dying
I think you should realign your priorities.
