DELL OptiPlex 990 USFF i5-2400s 2.50 GHz 4 GB DDR3 320 GB HDD DVD-RW Windows 7 Pro 64-Bit

Ultra-Small Form Factor Desktop

The Dell OptiPlex 990 USFF is an ultra-small form factor desktop built for office tasks and basic home use. It ships with Windows 7 Professional 64-bit pre-installed and an Intel Core i5-2400s processor running at 2.50 GHz. The system includes 4 GB of DDR3 memory and a 320 GB hard drive for local storage. A 16X DVD-RW drive handles optical media.

Suited for Light Workloads Only

This configuration fits users who need a compact PC for document editing, email and web browsing. The integrated Intel HD Graphics 2000 supports basic display output but cannot handle modern gaming or intensive 3D rendering. Buyers who want more storage or faster memory performance should look at other systems. The small chassis limits internal expansion options significantly.

Steady Performance in Confined Space

Under sustained load the low-power i5-2400s maintains its 2.50 GHz clock within the tight thermal envelope of the USFF chassis. The integrated Intel 82579LM Gigabit Ethernet controller provides a stable 10/100/1000 wired connection for long transfers. Rear eSATA and USB 2.0 ports allow external storage without adding internal heat. The included WiFi USB adapter offers wireless flexibility for persistent network tasks.
