I've got some on my monitor too.

Out of interest does anyone know if the PSU is in that new MacPro casing?

Always thought the Cube looked cool, until I found out that the reason Apple were able to make it so small and elegant was by having the power supply as a completely separate unit, that was almost the same size as the cube itself but with none of the finesse.

I think this Mac Pro means I'll be getting a Mac mini. I don't need the processing power and it's the pci slots and hard drive bays of the tower configuration that I was waiting for.

Looks like it. The plug into it looks like a standard 'kettle plug'. You don't tend to get those if you're plugging an external PSU in.

To be honest, I think that may possibly affect the system's cooling efficiency.

Or is the cat an additional heat sink? ;)

I wonder how many Mac Pros will be felled by act of cat.

Hah! "That's an unusual design Mr. Ive but if you say do..."

Though frankly you'd be amazed how much heat a sleeping cat kicks out. First time I put my hand on one I had to check it wasn't plugged into something.

Though the bigger question will be will cats be covered by Apple Care?

Interesting, Thunderbolt 2 is no faster than Thunderbolt 1. The 20gbps speed is achieved by bonding 2 channels together to provide two 10gbps channels that are synchronised with each other.

A 4K monitor needs a data transmission speed of 15gpbs.

That is how they get the "can drive 3 4K monitors," the Mac Pro will have 6 10gbps Thunderbolt 2 ports, which when they are all driven in pairs, provides enough throughput over the 3 pairs of bonded channels to provide the throughput needed.

That also means that there is also bog all bandwidth left for external storage or externally attached PCIe devices, such as media accelerators needed to accelerate video processing (as opposed to generating video output).

I was under the impression that the 20gbps figure was derived by combining the 10gbps from the PCIe side and the 10gbps from the displayport side to give an aggregated 20gbps but apparently not (anandtech article).

Whether or not you'll be able to run all 6 TB2 ports at full speed will depend on how they've divided up the PCIe bandwidth between the GPU's and the TB controller(s).
IvyBridge EP will provide the same PCIe bandwidth per CPU as the existing SandyBridge EP chips (40 lanes per socket). If they need to provide 20gbps of bandwidth for each TB2 port they'd need to use up 12 PCIe3 lanes. That would leave them with 28 lanes of bandwidth to connect the 2 gpu's and the PCIe based storage. Given that they'd need 2 lanes for the storage they'd have 26 lanes left for the GPU's which I suspect would be more than sufficient not to throttle even a a couple of top end firepro gpus.
