The bolded is interesting given what AMD just announced...New info...
New Mac Pro revision waits on Sierra GM. Inventory builds for expected demand.
Dual full-length graphics cards installed in every build resemble AMD reference design with single 6-pin power socket. Apple-styled coolers are same color as tower exterior. Output is single row of four DisplayPort ports, maybe one HDMI, not close enough look to know. So far all towers built with two graphics cards.
One 120mm fan cools PCIe chamber but nothing like old Mac Pro. Uses clever flow pattern and open space is only for extra cards. Logic board PCIe power sockets are near graphics cards sockets with easy access and short and neat cables. Like I said before shape is not conventional tower at all. PSU is long thin shape for length of tower and I cannot see any fan. Maybe it is hidden.
CPU cooler is entire length of tower with one 120mm fan each end. Still cannot learn CPU part numbers but look at Broadwell EP v4 parts list and easy to guess except for top end core count.
Who am I? No One.
