DELL OptiPlex 990 SFF All-in-One 22" 1920x1080 i5-2400 3.1GHz 16GB DDR3 128GB SSD

Dell OptiPlex 990 SFF All-in-One 22

This Dell OptiPlex 990 SFF All-in-One integrates a 22-inch 1920x1080 display at 60 Hz with a 2nd Gen Intel Core i5-2400 3.10 GHz processor, 16 GB DDR3 RAM and a 128 GB SSD. It ships with Windows 10 Pro 64-bit, a DVD-RW drive, USB keyboard and mouse. The compact form factor suits office desks, reception areas or education labs needing a ready-to-use desktop.

Sustained workload behaviour

The quad-core i5-2400 reaches 3.60 GHz Turbo Boost under load, while the Intel Q67 chipset and DDR3 memory maintain steady throughput for typical business applications. The 2.5-inch SSD keeps boot and file access consistent during long sessions. Integrated graphics and the 60 Hz panel limit extended 3D or video rendering tasks, so the system is best matched to document, web and legacy software workloads.

Upgrade context and fit

This unit replaces older tower-and-monitor setups where space, cable count and deployment time are constraints. The 128 GB SSD and 16 GB DDR3 cover mainstream productivity; buyers who want more storage or discrete graphics should consider a separate tower configuration. The included USB Wi-Fi adapter adds wireless flexibility without internal card installation.
