OptiPlex (a portmanteau of "optimal" and "-plex") is 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 currently[update] 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.

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 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.

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.

[37] They are based on the standard OptiPlex models with added features; such as a higher heat threshold, MIL-STD 810G testing[38] and powered USB/Serial.
