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

Apple iMac G5 17-Inch — Vintage PowerPC All-in-One

The Apple iMac G5 17-inch is a landmark in computer design history — a complete PowerPC G5 1.8GHz system elegantly concealed behind a 17-inch display. With 1GB DDR RAM and an 80GB HDD running Mac OS X, this is a genuine collector's piece for Apple enthusiasts and vintage computing fans. Backed by a 12-month Reboot IT warranty.

Key Benefits

  • Iconic Apple design: The iMac G5 pioneered the slim all-in-one concept that defined Apple hardware for decades
  • PowerPC G5 processor: IBM-built 1.8GHz G5 chip — a historically significant architecture that preceded Apple Silicon
  • Mac OS X compatible: Runs Mac OS X Tiger (10.4) and earlier — ideal for period-correct software and Classic Mac development
  • Collector's condition: Graded and tested by Reboot IT — a genuine vintage Apple piece in working order
  • 17-inch display: Original integrated LCD panel fully tested and functional
  • Complete system: Self-contained unit with speakers, optical drive, and USB ports — plug in a keyboard and go

Performance in Use

The iMac G5 occupies a unique place in computing history as the machine that demonstrated a complete desktop could be hidden behind a monitor. Running at 1.8GHz with 1GB of DDR RAM, it handles Mac OS X Tiger smoothly — web browsing via period-compatible browsers, iLife applications, document editing, and music playback all perform as originally intended.

For vintage Apple collectors, this unit represents the first-generation iMac G5 (A1058) — an important step in Apple's design evolution between the CRT iMac G4 and the Intel transition. Period software including early Final Cut Pro, Logic, and Classic Mac applications run natively on the PowerPC architecture.

This machine is ideal as a display piece, a working vintage computing station, or a development machine for those maintaining PowerPC-compatible software. Note: this machine does not support modern macOS and is not recommended as a primary work computer.

Frequently Asked Questions

What version of Mac OS X does it run?

The iMac G5 supports Mac OS X up to version 10.5 Leopard (PowerPC). It does not support Intel-based macOS versions including Snow Leopard and later.

Can I run modern software on this machine?

Modern browsers, Office, and most current applications do not support PowerPC or Mac OS X Tiger/Leopard. This machine is best suited for period-specific software and collector use.

Does it include a keyboard and mouse?

No. A USB keyboard and mouse are required. Original Apple USB keyboards and mice from the era work perfectly, as do modern USB HID devices.

Is the display fully working?

Yes, the integrated 17-inch LCD is tested and functional as part of our grading process.

What is the warranty?

All Reboot IT products include a 12-month warranty covering hardware faults. If a fault develops within 12 months, we repair or replace at no cost.

What are the shipping costs?

Shipping costs apply based on size and destination — rates are calculated at checkout.

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.
