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.

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

The Z640 54880 Rackable Minitower Workstation from HP delivers powerful performance in a rackable minitower form factor and is designed for professionals who require high reliability. The Z640 is well suited for tasks such as intensive graphics, 3D rendering, multimedia, and gaming, as well as science and engineering applications. The system is powered by dual 1.7 GHz Intel Xeon E5-2603 v4 6-Core processor which will allow you to run multiple applications simultaneously.

The 8GGB of 2133 MHz DDR4 ECC registered RAM allows the computer run multiple applications simultaneously and also to quickly access frequently-used files and programs. If you need to upgrade, this system supports up to 16GB per slot when using ECC registered RAM, or 32GB per slot when using Load Reduced (LR) RAM. As this RAM features ECC technology, it is able to help detect and correct the most common kinds of internal data corruption. This RAM is also registered and registered memory modules, also known as buffered memory modules, place less electrical loads on the memory controller and allow single systems to remain stable with more memory modules than they would have otherwise.

For long-term storage of your files, a 256GB Solid State hard drive offers quick access to your data. If you want to add external storage drives or other peripherals, the Z640 features 8 x USB 3.0 ports and 2 x USB 2.0 ports. For users who wish to add additional components to the drive bays, the Z640 features two internal 3.5" drive bays and two external 5.25" drive bays. The NVIDIA Quadro M4000 graphics card features 8GB of dedicated video memory. It is designed to deliver a sharp, clear picture and allows for a wide range of monitors to be used via its two DisplayPorts and a DVI-I port. Whether you are listening to music, watching a movie, or playing a game, the integrated Realtek HD ALC221 outputs high definition audio and delivers higher fidelity than standard audio controllers.

The installed operating system is Windows 10 Professional (64-bit).

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.
