David. Try also searching for the boxed code (ADD3800CUBOX) rather than the tray code but watch out, they are as rare as hen’s teeth to buy unless you are called Dell. I have also heard that some retailers are taking orders when they haven’t got them in stock so check the feedback first. That may be why Froogle has delisted them. I’d like to go down the same route as you when the price drops a bit so if you manage to build it then call back and tell us all about it. dAVE.
