DELL OptiPlex 9020 SFF Desktop PC i5-4570 3.20GHz 32GB DDR3 1TB HDD DVD-RW Windows 10 Pro

Compact desktop for everyday office tasks

The Dell OptiPlex 9020 SFF is a small-form-factor desktop built around a 4th Gen Intel Quad-Core i5-4570 processor running at 3.20 GHz. It ships with 32 GB of DDR3 memory and a 3.5-inch 1 TB SATA hard drive. Windows 10 Pro 64-bit is pre-installed, and a USB keyboard plus mouse are included in the box. The integrated Intel Graphics 4600 handles standard display output over VGA and HDMI.

Simple component access inside the chassis

The SFF case opens without tools, exposing two memory slots and the 3.5-inch drive bay for straightforward upgrades. DDR3 modules must match the installed 32 GB capacity limit; inserting a different generation will prevent the system from booting. The half-height expansion slots restrict add-in cards to low-profile models only. The included 16X DVD±RW drive occupies the single external 5.25-inch bay.

Steady performance during extended workloads

Under sustained multi-tasking the i5-4570 maintains its 3.20 GHz base frequency without thermal throttling in the compact chassis. The 32 GB DDR3 buffer keeps virtual-memory paging to a minimum when many browser tabs and office applications run simultaneously. Integrated graphics share system memory, so prolonged 3D or video-encoding tasks will reduce available RAM for other processes. Gigabit Ethernet provides consistent wired throughput for long file transfers.
