OptiPlex (a portmanteau of "optimal" and "-plex") was a line of business-oriented desktop and all-in-one computers made for corporate enterprises, healthcare, the government, and education markets. Initially released in 1993 by Dell, these computers typically contain Intel CPUs, beginning with Celeron and Pentium and with the Core microarchitecture (i3, i5, i7, i9). Business-oriented components, such as Gigabit Ethernet, Display Port, tool-less Chassis and software such as data protection utilities, along with management features such as Intel vPro often come standard with OptiPlex systems. Their configurations can be completed by the purchaser for components such as CPU, GPU, RAM, storage and wireless options, as well as Dell Pro support.

History Dell released the OptiPlex and NetPlex lines in 1993 in the wake of its first quarterly loss. Its disappointing results were partially attributed to poor returns on its notebook division; however, Dell's desktop and server lines continued to see success, particularly within the enterprise market.

The new offerings were positioned accordingly. The NetPlex line consisted of inexpensive i486 workstations designed to be used as corporate network clients. The OptiPlex line offered the same networking capabilities as the NetPlex along with additional features such as VESA Local Bus expansion slots, expandable VRAM, and stronger processor models. It also targeted large enterprises with features such as embedded diagnostics.

On 6 January, 2025, Dell announced that they were consolidating their desktop and laptop product lines into three new simplified categories, with OptiPlex rebranding into Dell Pro alongside Latitude.

In January 2025 Dell announced a major restructuring that saw the demise of the OptiPlex brand, along with others. OptiPlex was folded into Dell Pro along with Latitude.

Series 3 Dell OptiPlex from 2005 to 2009 followed Intel's BTX standard. The first model to sport the new BTX layout was the uncommon BTX version of the GX280 The last model to be BTX is the OptiPlex 780. 7xx Series DT models can be configured with a riser card to accommodate two full height cards. The riser card fits over the top PCIe x16 slot and middle PCI which is slightly longer with extra pins, this is however not PCI-X. Features DirectDetect system health status indicators for troubleshooting and diagnostics.
