All-in-one computers are great–until you want to upgrade. Having to pry open a monitor/CPU combo is the kinda thing that gives Geek Squad geeks the shudders. That’s why the new HP Z1 Workstation is so refreshing. With configurations starting at $1899, the Z1 features a brilliant 27″ display with an easily accessed set of innards, allowing you to add a new HDD, upgrade the memory, or switch graphics cards without playing a high stakes game of PC Operation. In a few years, when the included Intel Xeon processor isn’t as sexy as it is now, you’ll be pleased as punch to not have to consider a whole new rig.
