Oh, probably-- two for sure, but there are plenty of hdds around there that are of questionable usability-- but would function fine in a 'home' setting. I could probably build a couple rigs with 3-5 hdds in em (we are talking prob 40 GB drives here).
You should see the pile of carcasses we have around there... we have taken out any expansion card, RAM, HDD, and dvd/cd drives out of em, but there are (easily) 30 empty rigs there, 30+ CRT's and a handful of lcd monitors. I have a kitchen sized garbage can full of power cords, cause there are so many extras around.
