Since you didn't give the model # of the cpu's, I'm going guess they are single-core from the P4 era. If that's the case, a current $400 desktop is going to be much more powerful than this. It would have more memory, more hard drive space, and the CPU would be at least a Core 2 duo, if not better. Besides, something is worth only what someone is willing to pay. I think you'd be really lucky to get $100, if that.
