Dell OptiPlex 755 (Ultra Small Form Factor), mounted on the back of a monitor

OptiPlex is a line of desktop computers from Dell aimed at the corporate, government and education markets. The systems typically contain Intel CPUs, beginning with the Pentium and currently with the Core i7 (as of mid-2014) although Dell sells some models with AMD CPUs as well. Business-oriented components, such as Gigabit Ethernet and software such as data protection utilities often come standard with the Optiplex. (Compare Dell's Dimension counterparts.) opiniam 5).

Capacitor issues[edit]

Older OptiPlex models (mostly produced in 2003 and 2004), notably the GX270, suffered from frequent failures due to faulty capacitors supplied by Nichicon. These capacitors would bulge and leak, resulting in product failure after only a few years of use. As of June 2013, there is still ongoing litigation regarding this problem, alleging that Dell knew that the computers were likely to fail, and continued to ship them.[1]

Name[edit]

OptiPlex is a portmanteau of "opti" (meaning optimal) and "plex" (meaning parts or units.)[2]

Chassis[edit]

The newest OptiPlex models break from Dell's proprietary form factors and follow, for the most part, the ATX standard, usually to the Mini-ITX form factor for SFF computers, and MicroATX form factor for DT and MT computers.

The OptiPlex series comes in various sizes which have evolved as the style of chassis has changed.

Classic beige[edit]

In the classic beige chassis:

Chassis Height Width Depth 5.25" external bays 3.5" external bays internal bays
Small form Factor 9.14 cm (3.6 inches) 31.75 cm (12.5 inches) 37.8 cm (14.9 inches) 1 slim optical 1.44 floppy (1) 3.5" HDD

Midnight-gray[edit]

In the recent midnight-gray chassis (with the flip-up door) (Transformer cases):

Chassis Height Width Depth 5.25" external bays 3.5" external bays internal bays

BTX (matrix cases)[edit]

Current model BTX chassis:

Chassis Height Width Depth 5.25" external bays 3.5" external bays 3.5" internal bays

Mini-tower (Matrix Smith Case) 41.4 cm (16.3 inches) 18.5 cm (7.3 inches) 43.9 cm (17.3 inches) 2 1 2 HDD

The OptiPlex 960 introduces a new style of cases, made to be eco-friendly with recyclable plastics. They are named after various rock bands (Bon Jovi, Mötley Crüe, Mr. Big).
