1) From looking at the guts of the new tube, I assume the power supply is external. I would think that this thing would need a 400-500W power supply. Anyone have an idea how big that will be?
There is a pretty good chance that the "cheese grader" thing when looking down from the top is the power supply stuffed between the CPU/Chipset board and the I/O output panel. ( go to the "Thermal core" picture which looks down from the top with the fan off.
Oriented it vertically allows it to ventilate its heat "up the chimney" too.
To run a 130W Xeon E5 and two 250+W AMD FirePro W9000 equivalents it is more like 700W ( given that some of the other things need power too. USB 3.0 and Thunderbolt power distribution among a few other things. )
The major other clue is the "Expansion, vastly expanded " picture. It shows the back panel. There is a standard three prong connector for a power cord right there.
2) I'm guessing that the top end machine 2-3GB FirePro, 12-core Xeon, 16GB RAM, and 1TB SSD, is gonna cost well in excess $5,000.
Probably 6GB FirePros and north of $5,000. The 12 core Xeon all by itself is probably around $1800-2100 before any Apple profit margin applied.
Apple always has crackhead pricing on max sized SSDs ( so something over $1K ) . And haven't even started to pay for the video cards ( and VRAM) yet.
That's top end BTO or "best " ( out of 'good' , 'better' , 'best') entry?
In order to hit the current $2500 price point I would think they would have to offer a single 1GB GPU, a 4-core Xeon, 4GB RAM, and 256GB SSD.
Probably cannot have on GPU. In order to hit the $2,500 price point Apple will have to struck a deal with AMD to make their own GPU cards more aligned with what the cards cost rather than AMD FirePro pricing structure.
Given that low end, and the option to get that in a classic MacPro tower, or a Tube which would you choose? I think that question would be a valid poll question.
It isn't likely the low end and won't get the same functionaly if decouple the GPUs ( since will loose the TB ports ).
I would hope that Apple would offer an updated mac tower, in addition to the new tube, and let the market decide which they want. But a MacRumors poll might tell which way the winds are blowing.
Winds blowing about alternative universes???? Apple has already sailed in their ship. It was a sneak peak, not a solicitation of votes of what they might do next.
There were 7 years of towers based on Intel from 2006-2013. The "voting" ( buying of systems ) has
already been done. The growth died and Apple moved on to something new.
