TL;DR: The Dell OptiPlex 3040 Micro packs an i5‑6500T, 8 GB RAM and dual video outputs into a 1.4‑in‑wide, 7.2‑in‑tall chassis for just $239.99, making it a space‑saving, budget‑friendly business desktop.

The standout dimension is its ultra‑narrow 1.4 in (36 mm) width and modest 7.2 in (183 mm) height, all while weighing only 2.82 lb (1280 g). Under the hood sits an Intel Core i5‑6500T with a 2.5 GHz base clock that boosts to 3.1 GHz, paired with 8 GB DDR3L‑1600 MHz RAM and a PCMark 8 score of 3087 points, delivering solid office‑task performance.

Compared with peers, the 3040 Micro is narrower than the GMKtec G3S Beats’ 156 mm packaging width and taller than its 44 mm height, yet it offers twice the USB 2.0 ports (2 vs. 1) and four USB 3.0 ports versus the limited listings of other models. At 2.82 lb it's dramatically lighter than the Dell OptiPlex 5040’s 13.0 lb and the Dell OptiPlex 5060’s 5250 g, though it's a bit heavier than the Kamrui Pinova P2’s 850 g. Its maximum memory of 16 GB DDR3L‑1600 MHz trails the 64 GB ceiling of the OptiPlex 5060, reflecting its budget‑oriented positioning.

Professional reviewers praise the generous port selection and tool‑less serviceability, noting the i5 CPU and 3087‑point PCMark result handle daily office workloads with ease. Users love the tiny footprint, quiet operation and VESA‑mount capability, but the most common complaint is the lack of built‑in Wi‑Fi—wireless requires an optional M.2 card. The system also relies on a 256 GB SATA SSD and can't accept an M.2 NVMe drive, limiting storage speed upgrades.

Best for: Entry-level buyers or those on a tight budget
