DELL OptiPlex 3040-Micro i7-6700T 16GB 256GB desktop PC

Compact Mini PC for Office Work

The Dell OptiPlex 3040-Micro is a tiny desktop computer built around an Intel Core i7-6700T processor with 4 cores and 8 threads. It ships with 16GB of DDR4 memory and a 256GB SSD, running Windows 11 Pro out of the box. The integrated Intel HD Graphics 530 drives displays via HDMI and DisplayPort, while Wi-Fi and a single RJ45 port handle networking. A wireless keyboard and mouse are included for immediate use.

Simple Setup with Limited Expandability

Installation is straightforward: connect power, attach a monitor using the HDMI or DisplayPort output, and pair the included wireless peripherals. The Mini PC form factor uses an external power adapter, so there is no internal PSU to mount. Because the chassis is very small, adding internal storage or expansion cards is not practical; buyers who need more storage or a discrete graphics card should consider a larger tower system.

Steady Performance for Daily Tasks

The i7-6700T runs at a 2.80GHz base frequency and can reach 3.60GHz on turbo, with an 8MB cache to help sustain throughput during extended workloads. The low-power design keeps thermals manageable inside the compact case during long office sessions, web browsing, or video playback. Integrated graphics performance remains consistent for typical productivity applications but is not suited for heavy 3D rendering or modern gaming loads.
