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 ProDesk 400 G6 Mini — 6-Core Compact Business Desktop

A powerful yet tiny 1-litre desktop built around a 6-core Intel Core i5-10500T, 8GB DDR4 RAM, 512GB NVMe SSD, Wi-Fi 6, and Windows 11 Pro. Professionally tested by Reboot IT and backed by a 12-month warranty — with free standard AU shipping.

Key Benefits

  • 6-Core 10th-Gen Performance: The i5-10500T packs six cores and twelve threads into a 35W envelope, boosting to 3.8GHz — real multitasking muscle in an ultra-small chassis.
  • 512GB NVMe Storage: A large, fast NVMe SSD gives you ample room for documents, applications, and local data — and boots Windows 11 in seconds.
  • 1-Litre Mini Form Factor: Smaller than a hardcover book, this machine mounts behind a monitor on a VESA arm, sits under a stand, or disappears into a cabinet — with no compromise on performance.
  • Wi-Fi 6 Built In: Intel Wi-Fi 6 (802.11ax) and Bluetooth 5.1 are standard — no USB dongle needed for fast, stable wireless networking.
  • Dual 4K Display Support: Drive two 4K monitors simultaneously via DisplayPort and HDMI — a full productivity workstation from a box the size of a lunchbox.
  • Windows 11 Pro Ready: Ships with a genuine Windows 11 Pro licence, including BitLocker, Remote Desktop, and Group Policy — the features IT departments depend on.

Performance in Use

The ProDesk 400 G6 Mini punches well above its size. Six cores and 12 threads with Turbo Boost to 3.8GHz handle the full office workload — dozens of browser tabs, large Excel models, Teams or Zoom calls, and cloud-based line-of-business applications — without the machine breaking a sweat. The 8GB of DDR4 keeps daily multitasking responsive, and there is room to expand to 64GB if your workload grows over time. The 512GB NVMe SSD is the real daily-use differentiator: Windows 11 boots fast, applications launch almost instantly, and file operations feel immediate.

Reception desks, admin stations, point-of-sale back-ends, classrooms, home offices, and call centres are natural homes for this machine. Its 1-litre footprint frees up desk space without sacrificing capability, and the dual 4K display outputs mean you can run a full two-monitor workstation from a single, silent little box. Wi-Fi 6 delivers fast, reliable wireless networking without any USB adapter, while Gigabit Ethernet is there when you want a wired connection for maximum stability.

The i5-10500T runs at 35W TDP — it stays cool and quiet under typical office load. There is no GPU fan ramp-up, no heat buildup on the desk, and the machine runs silently in all but the most sustained CPU-heavy tasks. For any business or home office that wants real performance in minimal space, the ProDesk 400 G6 Mini is a compelling choice.

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.
