EX-GOVERNMENT · TOWER / SFF / MICRO

Refurbished Dell OptiPlex Desktops.

Q: Which OptiPlex form factor should I choose?

A tower for expansion, an SFF for a compact office desktop, or a micro for the smallest, quietest option. All three deliver the same core performance for office work.

Q: Can I upgrade the RAM or storage?

In most cases yes, especially tower and SFF models. We can fit extra RAM or a larger SSD before despatch.

Q: What does ex-government mean?

Machines retired from government and corporate fleets well before the end of their working life. Data is securely wiped and the unit is refurbished and graded before resale.

Q: What is the difference between the OptiPlex 3000, 5000 and 7000 series?

They are Dell's good-better-best tiers. The 3000 covers everyday office work, the 5000 adds performance and features, and the 7000 is the top tier for power users. For most buyers a 3000 or 5000 with an i5 and 16GB RAM is the sweet spot.

Q: Does a Dell OptiPlex come with a monitor?

No. The OptiPlex is the desktop unit only - connect your own monitor, keyboard and mouse, or add a refurbished monitor. All-in-One OptiPlex models include a built-in screen.

The workhorse of Australian business and government IT — which is exactly why it makes the best refurbished desktop you can buy. Over-engineered for reliability, retired in bulk, passed to you in excellent condition.

FAQ

Questions, answered.

Is a refurbished Dell OptiPlex reliable?

Very. The OptiPlex is a business-class machine built for years of daily use, then retired from corporate and government fleets while still in excellent condition. Every unit passes our 20-point inspection and carries a 12-month warranty.

Which OptiPlex form factor should I choose?

Choose a tower if you want room to expand, an SFF for a classic compact office desktop, or a micro if you want the smallest, quietest option. All three deliver the same core performance for office work.

Does it come with Windows?

Yes. Every OptiPlex ships with Windows 11 Pro pre-installed and updated, including BitLocker and enterprise security.

Can I upgrade the RAM or storage?

In most cases, yes — tower and SFF models are especially upgrade-friendly. We can fit extra RAM or a larger SSD before despatch; just ask when you order.

What does “ex-government” mean?

These machines came from government and corporate fleets that retire hardware on a fixed cycle — well before the end of its working life. The data is securely wiped and the unit is professionally refurbished and graded before resale.

What warranty and grades are available?

A 12-month hardware warranty with shipping both ways on claims. Grades run Premium, Excellent, Good and Acceptable — all to the same inspection standard.

What is the difference between the OptiPlex 3000, 5000 and 7000 series?

They’re Dell’s good-better-best tiers. The 3000 series covers everyday office work, the 5000 adds a little more performance and features, and the 7000 is the top tier for power users. For most buyers a 3000 or 5000 with an i5 and 16GB RAM is the sweet spot.

Does a Dell OptiPlex come with a monitor?

No — the OptiPlex is the desktop unit only. Connect your own monitor, keyboard and mouse, or add a refurbished monitor to your order. All-in-One OptiPlex models do include a built-in screen.

OptiPlex or a mini PC — which should I choose?

The OptiPlex Micro is a mini PC, so it comes down to size and expansion. Choose a Tower or SFF if you want ports and room to upgrade; choose a Micro or a wider mini PC if space and silence matter most. Our mini PC buying guide compares them in detail.
