The newly announced HP Z1 all-in-one workstation is smaller than its predecessors but hides quite powerful capabilities inside.  You can choose between a Skylake or Xeon E3 chip from Intel, 32 or 64GB of RAM and you can add in a pair of HP Z Turbo Drive PCIe SDDs to complement the installed HDDs.  The screen is 4k, but of a slightly smaller size than previous models at 23.6" which may deter some previous owners from upgrading, support for NVIDIA's new Maxwell chips may change that opinion.  For peripherals, there are a pair of Thunderbolt 3 ports, Type-C form factor for those of you whom this is of prime importance.  As you can see from the picture at The Inquirer, these AIO's are designed to be user serviceable and you can upgrade most of the components after you have purchased the machine.

"HP INC has unveiled its third-generation Z1 workstation, having given it a boost with more memory, more storage and the latest Intel processors. "
