Dell OptiPlex 7040 Micro Mini PC i5-6500T Quad Core 8GB 256GB SSD Win 10 Pro Wty
Dell OptiPlex 7040 Micro — Compact Business Desktop
A quiet, 1.8-litre business desktop built around a quad-core Intel Core i5-6500T with 8GB of memory and a 256GB SSD, running genuine Windows 10 Pro. Supplied with a 12-month Reboot IT warranty.
Key Benefits
- Fits anywhere — at roughly 1.8 litres it sits behind a monitor, under a desk or on a shelf — it takes back the space a tower used to occupy.
- Genuinely quiet — the 35W T-series processor runs cool, so the fan stays near-silent in reception areas, consulting rooms and shared offices.
- 256GB solid-state storage — boots in seconds and stays responsive — the single biggest real-world difference over an older mechanical-drive desktop.
- Dual 4K display support — DisplayPort and HDMI drive two independent screens, which is the layout most admin and data-entry work actually wants.
- Room to grow — two SO-DIMM slots take up to 32GB, and both M.2 and 2.5" drive bays are accessible without tools.
- Business-grade, not consumer — vPro-capable chassis, metal construction and Dell commercial build standards — designed for years of daily use, not a two-year consumer cycle.
Performance in Use
The Core i5-6500T is a quad-core 35W processor, and that low power figure is the point: it delivers full desktop performance without the heat or fan noise of a standard tower. For everyday business work — Microsoft 365, a dozen browser tabs, Xero or MYOB, a line-of-business application and a video call — it never feels like the limiting factor.
Paired with 256GB of solid-state storage, cold boot to desktop takes seconds and applications open immediately. If you are replacing a machine with a mechanical hard drive, that single change is more noticeable day to day than any processor upgrade, because it removes the pauses that make an older computer feel slow.
Where it fits best is the fixed desk that runs all day: reception, dispatch, admin, point of sale, a consulting room, or a workshop terminal. It handles dual monitors comfortably, disappears behind the screen, and draws very little power. Because the i5-6500T is a 6th-generation part it is not supported for Windows 11, so it suits internally-managed or single-purpose roles rather than general internet-facing use.

Frequently Asked Questions
What is included in the box?
The mini PC and a genuine Dell power adapter. Keyboard, mouse, monitor and display cables are not included unless separately listed.
Can I add more memory or storage later?
Yes. The OptiPlex 7040 Micro has two SO-DIMM slots supporting up to 32GB DDR4 total, plus an M.2 slot and a 2.5" bay, so the 256GB drive can be supplemented or replaced.
Will it drive two monitors?
Yes — DisplayPort and HDMI outputs run two independent displays at up to 4K, which is the most common use for this machine on a reception or admin desk.
Why Windows 10 rather than Windows 11?
The 6th-generation Core i5-6500T is not on Microsoft's supported processor list for Windows 11, so Windows 10 Pro is the correct and stable choice for this hardware. Microsoft security updates for Windows 10 have now ended, so this suits offline, single-purpose or internally-managed roles rather than general internet-facing use.
Is the operating system genuine?
Yes. Windows 10 Pro is installed and activated against the licence embedded in the unit.
How is data from the previous owner handled?
Every drive is wiped to a documented erasure standard before the operating system is reinstalled. Nothing from the prior deployment remains.
What are the delivery options?
Shipping costs apply based on size and destination — rates are calculated at checkout.
