I have a ton
of computer parts
that are obsolete
by today's standards
. That tiny 340-megger is gold
to someone who needs a computer.
When I fix or upgrade other people's computers, my fee is usually the old parts that are not wanted. I also make them watch me work so they can do it next time. I end up with enough computer parts to fill a house (just ask Yurei, hehehe).
You can take the "doorstops" and create a functional system. After they're up and running, you can donate them to local schools, child day care centers, abuse shelters, churches or even kids whose parents could never even consider purchasing a computer. Imagine how you would've felt if someone gave you a computer when you were a kid! You can help a child to improve his or her self-esteem, education and interest by donating that bookend. It won't be a top-end gaming system, but it can hold freeware games, free internet access accounts, Linux, word processors, etc.
