All-in-one computers eliminate desktop clutter by integrating the display and computer into a single unit. In 2026, the Apple iMac range dominates the AIO market with its striking design, the powerful M4 chip, and breathtaking Retina displays. For budget-conscious buyers, Amazon Australia also offers a strong selection of renewed iMacs and business AIOs that deliver excellent performance at significantly lower prices.
We've ranked the top 10 all-in-one computers available on Amazon Australia, from the latest Apple M4 iMac down to practical renewed options that represent exceptional value.
Amazon Renewed products are inspected, tested, and certified to work like new. For iMacs, renewed models can save you 30–50% versus buying new, while still delivering excellent performance. Apple Silicon (M1, M3, M4) renewed models are particularly compelling as even the older M1 remains capable for most tasks in 2026. Always check the seller's rating and Amazon's Renewed guarantee terms.
2. Apple Silicon vs. Intel: What's the Difference?
Apple Silicon (M1, M3, M4) delivers superior performance-per-watt compared to Intel models, with near-silent operation and faster general computing. Intel-based iMacs (i7/i9 models from 2020) still offer competitive raw performance for CPU-intensive tasks and can be more affordable as renewed units. For most users in 2026, any Apple Silicon iMac outperforms the older Intel models for everyday work.
16GB: Most users, video editing, creative apps, multitasking
24–32GB: Power users, 3D rendering, heavy video production, large projects
256–512GB SSD: Average users with cloud or external storage
1TB SSD: Heavy media users and professionals
4. Display Size: 24" vs. 27"
The 24" iMac with 4.5K Retina is ideal for most home and office setups. The 27" iMac with 5K Retina provides more screen real estate, better for professionals working with large canvases, multiple windows, or ultra-detailed media work. The 27" models are only available as renewed Intel units in 2026 (Apple discontinued this size after the M1 transition).
5. Australian Shopping Tips
Apple products rarely go on deep sale at Amazon Australia, but EOFY sales occasionally offer modest discounts on new models. Renewed iMacs fluctuate more, check prices over time for the best deals. Always verify GST-inclusive pricing and that warranty or Apple Care coverage is valid in Australia.

Frequently Asked Questions
Are all-in-one computers good for everyday use?
Yes, all-in-ones are well-suited to everyday computing for home and office use. They combine the monitor and computer into one unit, eliminating most cable clutter and saving desk space. Modern all-in-ones from Apple (iMac) and HP offer sufficient power for web browsing, office productivity, video calls, and light photo editing. The main trade-off is limited upgradability since most components are soldered to the motherboard. For users who are not planning upgrades and want a clean desk setup, an all-in-one is an excellent choice.
Can you upgrade RAM or storage in an all-in-one?
This varies significantly by model. Apple iMacs from 2019 onwards have RAM and storage soldered in with no upgrade options, making it essential to configure them correctly at purchase. Some HP and ASUS all-in-ones have accessible RAM slots and replaceable storage, though it requires opening the back panel. Always check the specific model's specifications before buying if upgradeability is important to you. As a general rule, spec up at purchase time rather than planning to upgrade later.
Is an all-in-one or tower desktop better for gaming?
Tower desktops are significantly better for gaming. They accommodate dedicated GPUs, support better cooling solutions, and are far easier to upgrade as new hardware releases. Most all-in-ones use laptop-grade or integrated graphics that cannot run demanding titles at acceptable settings. The iMac with its M-series chip handles gaming reasonably well for casual titles, but serious gaming requires a tower with a dedicated GPU. If gaming is a priority, buy a tower desktop and add a separate monitor.
How long do all-in-one computers typically last?
A well-specified all-in-one should remain useful for 5-7 years for everyday tasks. Apple iMacs tend to hold their performance longer due to Apple Silicon efficiency and extended software support. Windows all-in-ones follow a similar timeline though Windows software support for older hardware can become a constraint. The non-upgradeable nature of most all-in-ones means performance stays fixed at purchase specifications, so buying adequate RAM and storage upfront extends useful life significantly.
