DELL OptiPlex 7040 SFF i7-6700 3.4GHz 32GB DDR4 512GB NVMe Windows 10 Pro desktop PC

Small-form-factor business desktop

The Dell OptiPlex 7040 SFF is a compact business desktop built around a 64-bit quad-core i7-6700 processor running at 3.4 GHz. It ships with 32GB of DDR4 memory and a 512GB NVMe PCIe M.2 solid-state drive for fast boot and data access. Integrated Intel HD 530 graphics drive two DisplayPort outputs and one HDMI port. The system arrives with a fresh, activated install of Windows 10 Pro.

Straightforward setup with display-cable caveat

Installation consists of connecting power, peripherals and a compatible monitor cable; no internal assembly is required. The chassis uses a small-form-factor layout that limits internal expansion space compared with larger towers. A common issue is the absence of VGA or DVI connectors, so older monitors will need an active adapter or a different cable. The integrated graphics share system memory, reducing the amount available to applications.

Interface and upgrade limits

The Q170 chipset provides six USB 3.0 ports and four USB 2.0 ports for peripheral connectivity. Gigabit Ethernet tops out at 1000 Mbps for wired networking. The M.2 slot is occupied by the boot NVMe drive, leaving no spare M.2 socket for additional NVMe storage without removing the existing drive. Slim form-factor dimensions restrict graphics-card length and power, so discrete GPU upgrades are generally not practical.
