All-in-One PC with 19" Monitor

This DELL OptiPlex 790 USFF all-in-one PC integrates the computer components behind a 19-inch LCD monitor. It is powered by an Intel Quad-Core i5-2400 processor running at 3.10GHz with 8GB of DDR3 RAM. The system includes a 1TB hard drive, a 16X DVD±RW drive, and comes with Windows 10 Pro 64-bit pre-installed. It suits office workers or home users needing a compact, ready-to-use desktop setup.

Simple Setup with Included Peripherals

The unit arrives with a USB keyboard and mouse so you can start working immediately after connecting power. Installation is straightforward because the PC and display are already assembled as a single device. Expansion relies on legacy interfaces such as PCI, PCI Express x16, parallel and serial ports alongside multiple USB 2.0 ports. Buyers who need modern high-speed ports like USB 3.0 or USB-C will find those absent.

1TB Storage and 8GB Memory Headroom

The 1000GB hard drive provides ample space for documents, applications and media libraries. With 8GB of DDR3 RAM the system handles typical multitasking such as web browsing, office suites and video playback comfortably. Integrated Intel HD Graphics 200 and the 19-inch screen limit performance for modern gaming or intensive 3D work. Users who require dedicated graphics or more than 8GB of memory should consider a different platform.
