Apple is offering a $200 discount on their brand new 1.8Ghz SP G5s. They are in the "Sale" portion of the Apple Store where they usually have the refurbs. That brings the price down to $1899 (only $100 more than the 1.6Ghz single). For 200Mhz and three PCI-X slots I can't see a good reason for ANYONE to buy the 1.6Ghz machine anymore. Of course the refurb 1.8 Ghz G5s are only $1699. That seems like a pretty good deal.
