27-inch business all-in-one

This Dell OptiPlex 7770 integrates a 27-inch Full HD IPS display with an Intel Core i7-9700 processor, 8 GB of DDR4 memory and a dual-drive configuration of 256 GB M.2 SSD plus 1 TB hard drive. Windows 11 Pro is pre-installed alongside a USB keyboard and mouse, making it a complete desk-ready system for office environments.

8 GB DDR4 soldered memory limit

The unit ships with 8 GB of DDR4 SODIMM memory and the supplier notes a platform ceiling of 64 GB, so buyers planning heavy multitasking or virtualisation should verify upgrade headroom before purchase. Memory type is strictly DDR4; no other generation is compatible.

Fixed graphics and single-display output

Integrated Intel UHD Graphics 630 drives the built-in panel only, so users who need discrete GPU performance or multi-monitor setups should look elsewhere. The all-in-one form factor also prevents internal component swaps beyond memory and storage.
