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.

What payment options are available?

We offer a variety of payment options to make your shopping experience as convenient as possible! You can pay using all major credit cards, Apple Pay, Google Pay, Shop Pay, Afterpay, Zip Pay, and PayPal. If you prefer, we also accept bank deposits and even cash for in-store purchases!

Description

HP EliteDesk 800 G3 Mini — Business Compact Desktop

The HP EliteDesk 800 G3 Mini is a space-saving business desktop powered by a quad-core Intel Core i5-6500T (up to 2.50 GHz), 8 GB DDR4, and a 128 GB SSD. Running Windows 10 Pro in a compact 34 mm tall chassis, it suits any desk-space-constrained office environment. Backed by a full 12-month Reboot IT warranty and free standard AU shipping.

Key Benefits

  • Tiny footprint, full performance: Compact Mini chassis fits behind a monitor, on a shelf, or under a display via optional VESA mount
  • Quad-core 6th Gen CPU: i5-6500T handles Microsoft Office, browser workloads, video conferencing, and business applications reliably
  • SSD-equipped: 128 GB SSD delivers fast boot times and responsive application loading compared to older HDD-based systems
  • Dual-display output: Two DisplayPort 1.2 outputs support independent dual-monitor setups straight out of the box
  • Comprehensive USB connectivity: Front USB-C plus multiple rear USB 3.0 Type-A ports cover keyboards, mice, drives, and peripherals
  • Windows 10 Pro included: Pre-installed for familiar navigation, BitLocker encryption, and enterprise domain join capabilities

Performance in Use

In a typical small business or home office environment, the EliteDesk 800 G3 Mini handles Microsoft 365 (Word, Excel, Outlook), Teams or Zoom calls, web browsing, and PDF tasks smoothly. The SSD keeps the system noticeably faster than equivalent machines that shipped with hard drives, reducing boot time to under 20 seconds and eliminating lag when switching between applications.

For reception desks, education labs, or corporate hotdesks where desk real estate is limited, the G3 Mini’s slim 34 mm chassis can mount behind a VESA-compatible monitor entirely, removing the PC from the desk surface. The dual DisplayPort outputs let staff work across two screens without any adapters or docking stations.

The i5-6500T’s 35 W power envelope keeps fan noise low and energy consumption modest, making this a practical long-term choice for high-density office deployments.

Frequently Asked Questions

Does this come with a monitor, keyboard, or mouse?

No — this listing is for the mini PC unit only. Monitors, keyboards, and mice are sold separately.

Can I connect two monitors?

Yes. Two DisplayPort 1.2 outputs on the rear support dual independent displays simultaneously. DisplayPort-to-HDMI adapters work if needed.

Does it support Windows 11?

No — 6th Gen Intel processors do not meet Microsoft’s Windows 11 hardware requirements. This unit ships with Windows 10 Pro, which remains fully functional for everyday business use.

Can the RAM or storage be upgraded?

Yes. The G3 Mini supports up to 32 GB DDR4 via two SODIMM slots and has an M.2 slot for SSD replacement or upgrade.

What warranty is included?

A 12-month Reboot IT warranty covers all hardware defects from the date of purchase.

How does shipping work?

Free standard AU shipping is included. Orders are dispatched from Melbourne and fully tracked.

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.
