Paired with plenty of high-speed memory and a massive solid-state drive, you will enjoy fast load times and eliminate bottlenecks when jumping between your game library and broadcasting software.

Frequently Asked Questions

At Hungry PC we source quality, ex-lease business grade tech, not just old e-waste! Every unit is individually tested and cleaned, inside and out, with worn components replaced or upgraded as necessary to bring these systems a new lease on life. Used tech devices require a high level of professional servicing to ensure longevity and give you the best value possible. Our expert technicians with over 15 years experience place an extensive QA process to ensure the physical hardware is operating effectively as close to new as it can be. Often due to our processes, the upgrades we fit to these desktop and tower PCs make them function better than when they were brand new.

Why risk the problems of a completely unknown condition, pre-owned device that has never been serviced? You get much better value, longevity and certainty from a properly refurbished device.

Not all refurbished tech is the same, experience our difference and see how we grade our systems here

Yes! Your choice of Operating System version or distribution is installed fresh with latest Security Updates and Drivers. We can load Linux at no extra cost with your order! Simply select your preferred option from the Accessories / Upgrades section and we’ll ensure your machine is fully loaded with your ideal Operating System choice. Please note: This free service will add a little extra time to process your order. As Linux is a community supported operating system, driver/software support for Linux is at your own risk.

Yes! All our Desktops are covered by an industry leading return-to-base hardware warranty. In the very rare instance there was a problem with your desktop, we’re here to help. Read Warranty details here.

Get discounted repairs for life! With our commitment to sustainability, we are the first in NZ to offer our repair discount program. Simply by purchasing your PC from Hungry PC you’ll be eligible to receive 50% off our labour charges for any servicing or repairs to this device for 2 Years. This program rewards our loyal customers the benefit of cheaper repairs on any out of Warranty services required including accidental damage to the device, etc. Extend your warranty with us and we increase this discount program for the usable lifetime of the device.

Businesses demand reliability and usually take care of and maintain equipment to a high standard throughout their life. We’ve fully refurbished these machines after coming off lease, from use in a corporate environment.

Through refurbishment each machine is individually checked, and thoroughly tested in house. We then find our refurbished machines have a very low failure rate, even compared to when they were new. This is because factories do not often test each unit individually. In our experience these units will perform as good, if not better than when they were new.

Buying refurbished not only saves you money, by getting a better computer at a cheap price. It also supports a sustainable environment and reduces landfill, which we think is awesome!

Since buying a Refurbished PC can save you a lot of money and provide excellent performance, we feel they are a great idea not only for your bank balance, but also for the environment. By reducing ewaste and keeping these devices from landfill, we repurpose and renew them, to ensure they can bring a great deal of enjoyment to someone who is looking for a machine that can fit into any budget.

We strive to source the highest quality, business grade, ex-lease equipment. Instead of selling ordinary consumer grade equipment, we focus on machines that are designed for the corporate world. These computer systems have higher build quality, more reliable parts, and typically more powerful specifications. After our extensive testing process, we can be sure the machine will last the test of time. We have had many customers return to us and buy computers years after their first purchase, as they were impressed with the reliability and want to upgrade to their next, newer, fancier and faster machine.

We try to make things super simple, once your machine arrives you’ll find a FREE WiFi Adapter included in the package, alongside a Power Cord. Next steps are to simply connect these along with your Keyboard, Mouse and Monitor into the unit. You can either use your existing Keyboard, Mouse and Monitor to effectively treat our refurbished PC as an “Upgrade Box” or these can be purchased as an extra with your order. Check out our range of accessories here.

Once you have everything connected, you can turn on the machine and enjoy it, the rest has been done for you already, operating system will be loaded, ready for you to connect to your WiFi and install your programs, check your emails and browse the internet. Easy!
