When I first statrted out in this hobby of ours, I used Freecycle to gather up old computers too.
However, after a while, you realise that unless you are collecting a truckload, it just isn't worth your time and petrol doing so.
I live in the UK and petrol has just passed the $8/gallon mark.
I also had the problem of disposing of the monitors too.
It's getting cold here now so i'm moving away from refining and back into recoveriy until next spring.
I call the local schools and small to medium size companies who have always got broken and unused equipment lying around and they are normally very happy to let you call and collect it all.
I found that the large companies tend to insist on paying regulated disposal companies to collect their waste, they won't entertain people like me.
I've never used craigslist but i guess the same problems arise.
Have fun with the 14 computers you just found though, should keep you busy for a bit!
