I Guess its supply and demand, try and get one anywhere else and I think you will struggle to get on before next year, looks like they have all pretty much gone here also now anyway.
I would wait until they are in stock and see what the prices are before passing any judgement. Dont forget that you will have to add delivery at many of the "other" suppliers" when they have had your money for a while and finally get some stock.
Not done any posts here for quite some time, but I am in the market for a new home server case and I think this would be just the ticket myself !
