PC recycling should be a big business.
Meanwhile, I just discovered that my Microtek ScanMaker E3 scanner was dead due to sitting on the desk for a long without using it. It's possible to fix it but I don't think I'm going to use it. There's also a HP inkjet printer sitting on the shelf as well as a CRT and a '97 PC.
I did a search about recycling them. Hp.com looks like a better way to go IMHO. My plan is to take the scanner and printer first and see.
