Purpose-built business desktop

The Dell OptiPlex 7770 is a 27-inch all-in-one PC with a Full HD IPS display, an 8-core Intel i7-9700 processor and 16 GB of DDR4 memory. It ships with a 512 GB M.2 SSD plus a 1 TB hard drive, Windows 10 Pro, and matching USB keyboard and mouse.

Who this suits

Teams needing a compact, cable-free workstation for office applications, video calls and multi-monitor setups will value the integrated webcam, Bluetooth 5 and DisplayPort output. Buyers who require discrete graphics, user-upgradeable graphics or a chassis that accepts standard ATX components should consider a tower system instead.

Build integration

The unit occupies a single desk footprint and needs only a power cord, freeing space for peripherals. Its USB Type-C Gen 2 port, three USB 3.1 Gen 1 ports and two USB 3.1 Gen 2 ports handle docks, storage and input devices, while Gigabit Ethernet and Wi-Fi cover wired and wireless networks.
