PC Perspective posted a review on the HP Z1 Workstation 27-in All-in-One System

While consumers know HP for its substantial market share in the world of desktops and notebooks, perhaps more important to HP's bottom line is the company's server and workstation business. While we all know what servers do there might be some confusion about what a workstation is and what it does.

Workstations are usually defined as computers used by content creators and despite that fact that you burned that DVD of your family vacation, that's not quite the same. Brands like Xeon, Quadro, FirePro and Opteron are what you will find different in a workstation class computer versus a standard computer or laptop. And while technology enthusiasts will debate the actual differences between these components, the fact is that the market demands them.

Today we are taking a quick look at the HP Z1 Workstation, a unique workstation in that it resides in the shell of an all-in-one computer. But not just your normal AIO - this is a 27-in 2560x1400 display with a chassis that opens up for easy access to components inside.
