I predict a “Towertosh” hacking movement to rip the parts out of them and mount in something like a Cosmos II case. Hopefully enough SATA ports on the board to be useful or SATA card option as well as replacing the GPU. The AMD thing is really a puzzler though – surely they will have a nVidia option but again, hopefully hackable.
Also, no mention of non Xeon CPU’s. The lack of Sandy Bridge or Ivy Bridge “E” processors is such a huge gap in their CPU. It’s like Apple genetically is opposed to good price/performance numbers.
And not until Fall – will anyone care by then?
