Dell Refurbished All In Ones

30 products

Refurbished Dell OptiPlex all-in-one computers build a business-class PC into the display, so each desk runs on one power cable instead of a tower, a monitor and the wiring between them. Every unit is Grade A refurbished and ships with genuine Windows Pro installed.

Choosing a Dell OptiPlex All-in-One

Screen size sets the footprint. Smaller all-in-ones suit reception desks, classrooms and shared stations where space is tight. Larger screens give more room for spreadsheets and side-by-side windows. Processors range from low-power chips built for compact systems to full desktop processors for heavier office workloads.

Processor Generation and Windows 11

Windows 11 officially supports Intel 8th-generation processors and newer. For a home or home-office PC, that means a fully supported operating system with ongoing updates. For a business, it often decides whether a unit meets IT policy, so check the processor generation before ordering either way.

All-in-One or Desktop and Monitor

An all-in-one trades expandability for a cleaner desk: there's no room for a full-size graphics card, and a screen fault takes the computer out of service with it. If you'd rather replace screens and computers separately, refurbished Dell desktops pair with any monitor, and our guide to desktop form factors walks through how tower, small form factor, micro and all-in-one designs compare. If you're weighing Dell against HP and other brands, refurbished all-in-one computers cover the full range.

Frequently Asked Questions

OptiPlex is Dell's business desktop line, built for offices, schools and government fleets that need the same model across many desks. Consistent parts and drivers within each model make a refurbished OptiPlex all-in-one a predictable choice for standardized setups. For 3D or video work, check the graphics configuration first.

It depends on the generation. OptiPlex all-in-ones with Intel 8th-gen or newer processors meet Windows 11's requirements and stay current for office software. Older generations aren't officially supported on Windows 11, which matters for home users who want ongoing updates and for businesses whose IT policy requires a supported operating system. Processor generation is the quickest way to tell the two apart.

For office, reception and classroom use, yes. An OptiPlex all-in-one saves desk space and cabling, and business models hold up to daily use. The trade-off is repair and upgrade flexibility: a separate desktop and monitor can be replaced piece by piece, while an all-in-one is serviced as one unit.
