Frequently asked questions

What does the warranty cover?

Our warranty covers all hardware faults, but please note it doesn’t cover accidental damage or software issues. However, we’re here to help with technical support for those matters!

What is a refurbished device?

A refurbished device is a pre-owned item that has been restored to meet high-quality standards. At Reboot IT, we adhere to strict quality guidelines, ensuring that our refurbished products are not the same as used or secondhand items. We meticulously clean, test, and assess each device, replacing worn parts with high-quality components.

Unlike used items, which lack guarantees and rely solely on the seller's word regarding condition, refurbished devices come with assurance of quality and reliability.

Description

HP EliteDesk 800 G3 Mini — Enterprise Performance in an Ultra-Compact Chassis

  • Intel Core i5-6500T (6th Gen, 4 cores, 2.5–3.1GHz) — quiet, efficient quad-core performance at just 35W TDP
  • 8GB DDR4 RAM for smooth multitasking across everyday business applications and web-based workflows
  • 180GB SSD delivers fast boot times and snappy application launches throughout the workday
  • Windows 10 Pro with BitLocker, Remote Desktop, and Active Directory domain join support
  • Ultra-compact Mini form factor — under 1 litre in volume, fits behind a monitor or on any desk
  • DisplayPort and USB 3.0 ports for modern display and peripheral connectivity

The HP EliteDesk 800 G3 Mini packs enterprise-grade business computing into a chassis so small it holds less than 1 litre of volume. At 35W TDP, the Intel Core i5-6500T runs quietly and efficiently — making this an ideal desktop for open-plan offices, meeting rooms, point-of-sale setups, and any environment where noise and space constraints matter.

Despite its diminutive size, the G3 Mini handles the full range of business productivity tasks: web browsing, email, Office applications, video conferencing, and remote desktop sessions all run smoothly. Windows 10 Pro ships pre-installed, giving IT teams the enterprise management tools — BitLocker, Remote Desktop, Group Policy — needed to deploy it at scale without extra configuration overhead.

Is the HP EliteDesk 800 G3 Mini Right for You?
Great for Space-constrained offices, digital signage, meeting rooms, and kiosk deployments
Also suits IT teams needing a quiet, low-power business desktop for remote or VESA-mounted use
Consider instead The G3 USDT or G5 SFF if you need more storage, RAM expandability, or PCIe expansion
Not suited for Heavy multitasking, large storage requirements, or applications needing a discrete GPU
Condition Grades
Excellent Excellent to very good cosmetic condition. May have light scratches or minor blemishes. Fully tested and functional.
Good Good cosmetic condition with visible signs of prior use. May have scuffs or scratches. Fully tested and functional.

Frequently Asked Questions

Can the G3 Mini be VESA-mounted behind a monitor?
Yes — the HP EliteDesk 800 G3 Mini is compatible with an optional HP VESA mount bracket (not included) that attaches directly to any VESA 100mm monitor mount point.

Can I upgrade the RAM or storage?
The G3 Mini supports up to 16GB DDR4 across two SODIMM slots. The M.2 slot accepts standard NVMe or SATA SSDs for storage upgrades. Note the compact chassis limits heat dissipation — verify TDP compatibility for any replacement drives.

Does this support Windows 11?
The Intel Core i5-6500T (6th Gen) does not meet Microsoft's official Windows 11 hardware requirements. This unit ships with Windows 10 Pro, which receives security updates until October 2025. Organisations with extended support arrangements or alternative upgrade paths may still consider this a viable platform.

12-Month Warranty Included

Every HP EliteDesk 800 G3 Mini sold by Reboot IT is fully tested before dispatch and covered by our 12-month warranty. We're a Melbourne-based business committed to quality refurbished IT at honest prices.

All-in-one Solution for Home Office

I was looking for an in-expensive all-in-one solution for my home office to replace my existing desktop and monitor. I found this EliteOne 800 on reboot IT for under $200. I wasn't sure what to expect. It arrived within two days!!!! I upgraded the RAM, replaced the HDD and installed Windows 11. This is unbeatable value and was the cheapest price online. Coupled with a 3-month warranty, Reboot IT are by far the best online refurbished retailer I have used. Awesome!

Fair tech for price

Fair tech for price, good specs for era, serves the purpose. The black keyboard is an interesting rubber like texture clearly by design to pad the screen and avoid the keyboard touching. Screen is great. Still looking for magic formula to enable computer use in the bright bright sunshine. Keyboard taps are loud for someone who likes silent touch. The perfect PC has to exist, like build a bear.

Works excellently as advertised.

The laptop was sold with a warning about worn keycaps. In fact they had been obviously vandalised (ex school laptops, perhaps?). The keyboard worked fine, and the rest of the laptop too. I'm using it as a file server, so I don't need the keyboard much. So very pleased, and also pleased with reboot-it's service - as always, excellent, and quick responses to any queries.
