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!

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.

Description

Lenovo ThinkCentre A58 SFF — Pentium E5400, 4GB, 500GB

The Lenovo ThinkCentre A58 is a compact small form factor desktop built on the dual-core Intel Pentium E5400 with 4GB RAM and a 500GB hard drive. It ships with no operating system installed, which makes it a low-cost base for a lightweight Linux build, a kiosk or a legacy application host. Backed by a 12-month Reboot IT warranty.

Key Benefits

  • Lowest-Cost Working Desktop: This is entry-level hardware at an entry-level price — a complete, tested, warranted desktop for roles where a modern machine would simply be overkill.
  • No OS — Install What You Need: Ships clean. A lightweight Linux distribution such as Lubuntu, Xubuntu or antiX runs well on this hardware and costs nothing.
  • 500GB Hard Drive: Generous local storage for file serving, media, backups or an archive box — far more capacity than the workload typically needs.
  • 4GB of Memory Fitted: Double the base configuration these shipped with, which is what makes a modern lightweight Linux desktop practical rather than painful.
  • Compact SFF Chassis: Small enough to tuck behind a monitor, under a counter or into a comms cupboard where a full tower would not fit.
  • Tested and Warranted: Every unit is bench-tested before dispatch and carries a full 12-month Reboot IT warranty — not sold as-is.

Performance in Use

It is worth being straightforward about what this machine is. The Pentium E5400 is a dual-core processor from 2009 running at 2.7GHz. It will not run a modern Windows desktop pleasantly, and it is not intended to. What it does do is run reliably, draw little power and cost very little to deploy.

The roles where it still earns its place are specific and real: a kiosk or signage player, a lightweight Linux terminal, a print or file server on a small network, a legacy application host that needs a serial or parallel port, a workshop or classroom machine where damage or theft would not matter, or a spare that sits in a cupboard until something else fails. With 4GB of RAM and a lightweight Linux desktop such as Lubuntu or antiX, everyday browsing and document work is genuinely usable.

The 500GB hard drive gives it more storage than the workload will ever need, which makes it a reasonable candidate for a small file or backup box. Fitting a cheap SATA SSD would sharpen it considerably if you want to push it further. Integrated Intel graphics drive a single monitor over VGA, and Gigabit Ethernet handles networking.

Frequently Asked Questions

What can I realistically use this for?

Lightweight Linux desktops, kiosks and signage, print or file serving on a small network, legacy applications that need old-style ports, or as a cheap spare. It is not intended as a modern everyday office PC.

Which operating system should I install?

A lightweight Linux distribution is the right answer — Lubuntu, Xubuntu, antiX or Debian with a light desktop all run well on a dual-core with 4GB. Modern Windows is not supported on this processor.

Will it run Windows 10 or 11?

No. The Pentium E5400 falls well outside Microsoft's requirements for both. If you need Windows, look at one of our Intel Core i5 desktops instead.

Can I fit an SSD?

Yes. A standard 2.5" SATA SSD with a mounting bracket drops straight in and will make a noticeable difference to boot and application load times.

Is a keyboard, mouse or monitor included?

No. This listing is for the desktop unit only. We can quote separately on refurbished monitors and peripherals if you need a complete setup.

What does the warranty cover?

The 12-month warranty covers all hardware components against defects and functional failures under normal use. Contact sales@reboot-it.com.au for a Return Authorisation if you need to make a claim.

What are the shipping arrangements?

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!
