BBP! Get one of these: http://www.frys.com/product/5466019?...tY4hoCEFLw_wcB Pull the old hard drive and connect via USB to your current computer. Copy the stuff you want...

Then, go here: http://www.dban.org/ and create a boot CD (assuming your old machines will boot to CD and that they have a CD). Boot the old computer with the original hard drive in place, and follow the instructions.

If you can't boot the old computer from CD, then perforate the old drives after you've gotten any data from them using your favorite method.

The rest of the machine can go to Goodwill - they will recycle and get what can be got from them financially.
