The trouble is that you can't take the money (even if they offered) because the money doesn't exist. Do you really think PC World is paying real money for this?
I am sure the companies are getting something out of it... Probably not more than the free advertising this lands them though. I suspect that's why the final parts list is not finalized... They are not 100% sure who is really going to deliver... They probably have good faith agreements on some of the parts for example, rather than firm commitments.
That doesn't reduce the value any... It probably would cost $35,000 if you bought everything at full retail value... Maybe $20,000 if you shop online. And you could probably sell it pretty easily for $10,000.. Or even part it out and sell it for $15,000+ on eBay. But that wouldn't be nice... It would probably make the people at PC World very sad.
