Dell OptiPlex 5270 AIO21.5" PC i5-9600 8GB 256GB NVMe SSD Win 11 Pro

Dell OptiPlex 5270 All-in-One — 21.5" Full HD Business PC

A complete business desktop in a single chassis: 6-core Intel Core i5-9600, 8 GB DDR4, a 256 GB NVMe SSD and a 21.5-inch Full HD display with integrated webcam and microphone. Runs Windows 11 Pro, secured by TPM 2.0, and backed by a 12-month Reboot IT warranty.

Key Benefits

• Six cores of 9th Gen power — the Core i5-9600 runs 6 real cores at 3.10 GHz base and turbos to 4.60 GHz, well ahead of the dual and quad-core machines usually found at this end of the market.
• One box, no clutter — display, computer, webcam, microphone and speakers in a single unit. One power lead and one network cable and the desk is done.
• NVMe SSD, not SATA — the 256 GB drive is an NVMe module on the PCIe bus, several times faster than the SATA SSDs fitted to most machines of this generation. Boot and application launches are near-instant.
• Genuine Windows 11 Pro — the 9th Gen processor and TPM 2.0 module both meet Microsoft's Windows 11 requirements, so this machine stays in support rather than stranding you on Windows 10.
• Room to grow — 8 GB is fitted as a single DDR4-2666 SODIMM, leaving one slot free. Adding a matching stick takes it to 16 GB and enables dual-channel memory for a genuine performance lift.
• Dual-screen capable — a DisplayPort output drives a second monitor alongside the built-in panel, which is the setup most office users actually want.

Performance In Use

For mainstream business work this machine has more headroom than most buyers expect. Six cores handle Microsoft 365, MYOB or Xero, a busy browser with twenty tabs open, and a Teams or Zoom call running alongside — all at once, without the stutter you get from a 2-core machine trying to do the same. The 4.60 GHz turbo matters for the single-threaded work that dominates an office day: spreadsheet recalculation, PDF rendering, database queries and report generation all finish noticeably quicker.

The all-in-one form factor is the real draw for reception desks, consulting rooms, nurses' stations, training rooms and any counter where a tower plus monitor plus cable loom is impractical. The integrated webcam and microphone are tested working, so it is ready for video calls out of the box without bolting a USB camera to the top of the screen. The 21.5-inch Full HD panel gives a comfortable pixel pitch — text stays sharp without display scaling, which matters if you run older line-of-business software.

Two things to size up before ordering. The 8 GB of RAM is adequate for standard office work but it is a single stick, so if your users are heavy multitaskers, budget for a second module — it is an easy upgrade with a slot already free. And this unit has no wireless card, so it needs a wired network drop wherever it lands. If the site has no Ethernet at the intended position, a USB Wi-Fi adapter solves it cheaply, but plan for it rather than discovering it on install day.

Frequently Asked Questions

Is the screen a touchscreen?

No. This configuration has a non-touch 21.5-inch Full HD panel. The OptiPlex 5270 was sold in both touch and non-touch builds — this is the non-touch version, so please don't rely on the product images, which are illustrative.

Does it have Wi-Fi?

No. This unit has no wireless card fitted — networking is wired Gigabit Ethernet only. If you need wireless, a USB Wi-Fi adapter is an inexpensive addition; just make sure a network point is available if you intend to run it wired.

Can I add more memory?

Yes. The 8 GB is a single DDR4-2666 SODIMM with one slot still free. Adding a matching 8 GB module takes it to 16 GB and enables dual-channel mode, which is the single best-value upgrade for this machine.

Can I run a second monitor?

Yes. There is a DisplayPort output on the rear that drives an external monitor alongside the built-in display. You will need a DisplayPort cable, or a DisplayPort-to-HDMI adapter if your second screen is HDMI only.

Are a keyboard and mouse included?

No — this listing is for the all-in-one unit, stand and power lead. Keyboards and mice are sold separately; get in touch and we can quote a set with your order.

Is the operating system genuine and activated?

Yes. Windows 11 Pro is pre-installed and activated against the machine's digital licence. The drive is securely erased and Windows freshly installed before dispatch, so there is no previous owner's data on it.

What does shipping cost?

Shipping costs apply based on size and destination — rates are calculated at checkout. Local pickup from our Melbourne warehouse is also available.
