From the ones I took apart, you should do better than 9.00. It's unfortunate that you made the mistake, but I really think you will be fine.
It it was me:
1. List them on CL for 15.00 a piece.
2. Get a good size box.
3. Start pulling the memory and motherboards, throw them in a box as you go, then send the box right away to a buyer to recoup your money.
I posted some pictures on just breaking down the computer parts.

After removing the higher dollar parts, you also have some copper in the monitor part, but I would take the lowest hanging fruit as quick as I could and get my money back.
