Rawko is a warehouse facility that buys and sells computer equipment by the truckload and pallet-full.
I have been inside the operation and they have electronic gear stacked to the (30' high) ceilings, mostly in wire cage type bins and on metal shelving.
When they find anything of value they pull it out and put it on ebay for a while. After it has sat around for some amount of time you can "make an offer" and they may take it.
After some amount more time, it will be sold to the 3rd world in containers.
They usually start by asking top dollar, and have a pretty good idea of what the market will bear. I have gotten a couple of "half-way decent" deals from them, but only because I am local and can save the shipping.
Now, if you wanted a hundred desktops with Pentium IIIs and 2GB hard drives, they could fix you up for cheap !
