You have to consider that the drives in an empeg don't add much value since they are almost an expendable commodity i.e. they go out of date reasonably quickly and are easily replaced. Sure there's a difference between a 200GB and 20GB empeg because of the price of the 100GB drives. But when you are talking 20GB vs 0GB there's not much extra room to move. How much can you get a used 20GB laptop drive for these days? $30-50? If that?

That said I would pay somewhere around US$300 I think for a driveless empeg. But then I'm cheap...
