Dell OptiPlex 990 USFF desktop

The Dell OptiPlex 990 USFF desktop is a compact computer built for everyday office and home tasks. It runs on an Intel Quad-Core i5 processor operating between 2.9GHz and 3.30GHz with 4GB of DDR3 memory. A 128GB 2.5" SSD provides the boot drive and Windows 10 Professional 64-bit is pre-installed. The ultra-small form factor saves desk space while including a DVD±RW drive.

Check power and expansion limits

Verify that your workspace has a standard mains outlet for the external power supply used by this USFF chassis. The compact case restricts internal expansion so confirm you do not need additional drive bays or full-height cards. Integrated Intel HD Graphics 2000 drives the video output; ensure your monitor matches the available port type. The system ships with a USB keyboard and mouse already included.

Included WiFi adapter and peripherals

A USB WiFi adapter adds wireless networking without occupying an internal slot. Bluetooth capability is also listed for connecting compatible accessories. The bundled USB keyboard and mouse let you start working immediately after connecting a display. Windows 10 Pro 64-bit with a Certificate of Authenticity is ready to use out of the box.

Questions about this item

What comes in the box and what must I add?

The system ships with the USFF chassis, 4 GB DDR3 RAM, 128 GB 2.5" SSD, 16X DVD±RW, USB keyboard, USB mouse, WiFi USB adapter, and Windows 10 Pro 64-bit pre-installed. A monitor and speakers are not included.

Should I pick the 4 GB DDR3 / 128 GB SSD configuration or look for more memory and storage?

The listed unit has 4 GB DDR3 and a 128 GB 2.5" SSD. If you run multiple browser tabs, office suites, or light creative apps, plan to add more DDR3 modules and a larger 2.5" drive.

How does the Intel HD Graphics 2000 / 2500 perform once the PC is assembled?

Integrated Intel HD Graphics 2000/2500 drives everyday desktop work, video playback, and dual-display output via the onboard ports. It is not suited for modern 3D titles or GPU-accelerated rendering workloads.
