HP Z is a series of professional workstation computers developed by Hewlett-Packard. The first-generation desktop products were announced in March 2009, replacing the HP 9000 xw series. The product line expanded to mobile with the announcement of ZBook in September 2013, replacing HP's EliteBook W-series mobile workstations. The Z workstations mainly compete against Dell's Precision workstations, Lenovo's ThinkStation and ThinkPad P series workstations, as well as Apple's Mac Pro and MacBook Pro.

An all-in-one computer is a type of personal computer that integrates the computer components, such as the CPU, monitor, and speakers, into a single unit. It occupies a smaller footprint than a desktop computer with a tower form factor, and also uses fewer cables.
