About the cost now, as you will notice I fully broke apart this enclosure and in fact I made a quick calculation of the materials cost. It is about 350-400 bucks. This specific RAID controller card alone costs $150 and say another $80-100 for the TB3 card. Chassis, power adapter, SATA expansion board and the front panel board are easily over 100 bucks. If you add into this cost the taxes, software development, the shipping and the labor cost along with the support cost (warranty, RMAs etc) then $700 don't sound so crazy, right? Unless you want the people that build those products to earn less than 3-5 bucks per day so you can get them with $500.
I happened to travel to China and visited several factories there, so I know first hand what low production cost means.
How much do you believe the phones that you all have worth as parts? I don't see many of you complaining though why pay an iPhone or a Samsung 2x or even 3x the price of its parts? So please do the math before you insult me by saying "Stating it isn't that much in the article shows which side of the fence you sit on".
