Compact all-in-one desktop for everyday computing

The Dell OptiPlex 990 SFF integrates a 22-inch 1920 x 1080 display with a 2nd Gen Intel Core i5-2400 processor running at 3.10 GHz. It ships with 8 GB of DDR3 memory and a 128 GB solid-state drive. Windows 10 Pro 64-bit is pre-installed, and a USB keyboard and mouse are included. The small-form-factor chassis saves desk space while providing a DVD-RW drive for legacy media.

Upgrade path from older Core 2

Moving from a dual-core or early quad-core machine brings four threads and a 3.60 GHz turbo boost that improves multitasking responsiveness. The jump is worthwhile when your current PC struggles with multiple browser tabs, office suites, or light creative tasks. If you already run a newer multi-core platform with faster storage, the performance gain will be limited.

128 GB SSD handles the operating system

The solid-state drive provides quick boot times and snappy application launches for daily workloads. With 8 GB of DDR3 RAM, the system manages typical multitasking comfortably. Storage headroom runs out once large media libraries, extensive game installs, or sizable project archives are added, requiring external drives or cloud storage for expansion.

Questions about this item

What desk depth does the 22" monitor and SFF base require?

The 22" 1920 x 1080 monitor and slim AIO base fit on a standard desk; allow roughly 22 inches of depth for the screen and stand combined.

Which screw or latch secures the 2.5" 128 GB SSD during installation?

The 2.5-inch SSD mounts in the internal drive bay using the single captive screw on the chassis floor; forgetting that screw leaves the drive loose.

When should the 8 GB DDR3 memory be upgraded to the 16 GB maximum?

Upgrade to 16 GB DDR3 when multitasking slows — the board supports two slots, so add a matching 8 GB module to reach the limit.
