Let me be clear about the situation here.
I have a local computer recycler. They're good people - a small nonprofit that refurbs and upgrades older machines and gives them to low-income families. They also recycle all their scrap and unusable machines and parts, and a scrap hauler pays them by the pound.
My neighbor was going to donate the entire machine to this local recycler. Because the machine is considered too old, and because the recycler doesn't give the families Macs (or at least doesn't give them pre-OS X Macs), they would have junked the entire machine, dumping it in the scrap pile for their hauler to pick up and pay them. (They might have salvaged the ATA HD, but at only 6GB I doubt even that.)
By taking it off my neighbor's hands, I am able to place the motherboard, CPU, RAM, PCI cards and L2 cache in a good Mac home.
In the near future I'm sure I'll also be able to place the CD drive and HD in good homes. And if past experience holds true, then someone will also want the PSU to revive his/her ailing 6400/6500.
Then I will take the remaining carcass to the local recycler.
At least that way most of the machine will be used, and it will help keep other 6400/6500s from the dumpster.
If I could sell these machines whole - heck, if I could even give them away - then maybe things would be different. But that's not the case in my area, and no one wants to pay for me to ship them a 50 lb. package - these machines aren't as collectible as similarly heavy units like, say, a WGS 9150 or a 9600/350.
So given the economic realities, and given what was going to happen to this machine otherwise, I think I'm doing the best I can.
Best,
Matt
