Understanding Cosmetic Grades: Excellent vs Good

Reboot IT grades this desktop as either Excellent or Good based on cosmetic condition. Excellent Grade desktops show minimal signs of use with no deep scratches, cracks, paint chips, or missing pieces—perfect for professional environments where appearance matters. Good Grade units remain fully functional but may display light scratches, minor case wear, small dings or dents, or small paint chips from normal use—ideal for home offices or workspaces where performance takes priority over pristine aesthetics. Both grades deliver identical performance and undergo the same rigorous testing process.

Since 2001, Reboot IT has been Australia's trusted expert in certified refurbished technology, utilising cutting-edge diagnostic testing software to evaluate every component. Each desktop undergoes our comprehensive Verified Reboot Refurb process, where we meticulously test all features and functions including the processor, memory, storage, CMOS battery, connectivity ports, graphics output, and audio systems. Our thorough testing protocol ensures this refurbished desktop meets stringent quality standards before reaching you.

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.
