How and to whom do I donate hard drives?

I’m working this summer in a server room cleaning organizing and fixing computers. I came across several 18GB hard drives. They are completely worthless to anyone after 1999 and selling on eBay for pennies. Because we need to get rid of them and they are still in the packaging, brand new, I would like to donate them to a cause that would fix up computers for less fortunate people.

What is a good and worthy cause willing to pick up possibly 30 to 50 small HDs?
