Anyone have a few old hard drives?

[David Kramer]

I'm going to be selling at the MIT Flea this month
(http://web.mit.edu/w1mx/www/swapfest.shtml).

I have two or three old, slow computers that are almost complete, but need hard drives. 
I would like to put hard drives in them and do a minimal Linux install, just to show
they work.  I'm only gonna charge a few bucks for these computers (it's more about
cleaning my basement than striking it rich), so I can't afford to pay for them, but if
anyone has a hard drive or two that's at least a gig, I would love to take them off your
hands.

Aside 1: If you have other computer crap you just want to go away, let's talk.

Aside 2: I'm thinking of buying one of those emergency car battery/AC inverter things,
in part to have it, and in part to demonstrate these computers with.  Any
recommendations?  Is that something that's rentable?
