Looking to donate used electronics to a good cause

So I'm sitting here at Chili's at 45th and Lamar, contemplating where to donate ~20x Dell 1708ftp monitors, ~20x docking stations, and ~20x 300 series Optiplex's. I could donate them to Goodwill, but I feel like there's a more direct "good cause" out there that could benefit from used, older equipment that is still functional. So if anyone has a serious good cause to donate to, please let me know via PM. Anything environmental friendly goes to the top of the list.
