There are tons of 3 year old PCs that can be usefull systems but get recycled, I don't think 10 year old systems are any better then the 3 year old PCs because they happen to be Macs.
I don't agree with the crush all the CRTs you want comment, there are plenty of proprietary monitors out there that are needed to keep old systems running correctly (special refresh rates, connector types, recolutions, scan rates etc).
Most of what we are talking about here are for collectors, not people who want a 10 year old machine to get on the net. Freecycle has plenty of more modern items free, craigslist has plenty of newer items cheap. The cost of brand new machines is under $500 with monitor.
