DELL OptiPlex 990 SFF All-in-One 22" 1920 x 1080 i5-2400 3.1GHz 8GB DDR3 256GB SSD Windows 10 Pro desktop PC

Compact All-in-One with 22" Display

The Dell OptiPlex 990 SFF All-in-One integrates a 22-inch 1920 x 1080 monitor with a 2nd Gen Intel Core i5-2400 processor running at 3.10 GHz, 8 GB of DDR3 memory and a 256 GB SSD. It ships with Windows 10 Pro 64-bit, a DVD-RW drive, USB keyboard and mouse, and a USB Wi-Fi adapter. The small-form-factor chassis saves desk space while delivering a complete, ready-to-use system for everyday office tasks and light multitasking.

Upgrade from older Core 2 or single-core desktops

Replacing a legacy tower that relies on mechanical drives and 4 GB of memory, this unit adds four threads, Turbo Boost up to 3.60 GHz and solid-state storage for noticeably faster boot and application load times. The jump is worth it when the current machine struggles with multiple browser tabs, document editing and video playback at the same time. Buyers who need discrete graphics, more than 16 GB of RAM or modern high-speed ports should look elsewhere.

256 GB SSD and 8 GB DDR3 handle typical workloads

The 256 GB solid-state drive comfortably holds the operating system, office suite and a modest library of documents and media, while 8 GB of DDR3 keeps several applications responsive. Memory can be expanded to 16 GB if the workload grows, but the two-slot limit and DDR3 interface cap further expansion. The integrated graphics and 60 Hz panel are adequate for standard business use, not for gaming or colour-critical design work.
