6 Best Linux Distros for Old Computers to Use in 2021

As the popularity of Linux continues to rise, more and more people are turning back old computers that have been sitting in their basements for a few years. Here’s which six distros you should consider before upgrading your computer!

The “lubuntu” is a lightweight Linux distribution that uses LXDE as its default desktop environment. It is designed for old computers and laptops, with the goal of making them usable again.

Linux Distros, or Linux Distributions, are both an operating system and a package management system based on the Linux kernel. The operating systems Windows and macOS, which are in charge of processing all of the integrated internal data resources for aggregating them, may reportedly only be utilized if the user obtains them directly from Microsoft or Macintosh. 

When it comes to Linux Distros, however, the definitions could not be more aligned. Linux Distros are a collection of entities bundled into a single operating system. They perform the same functions as conventional operating systems, but in a different way; they are the result of mathematical amalgamation. 

Do you have an old Linux laptop or PC that you don’t think will ever see the light of day? Why not resurrect it with one of the following Linux distributions?

Lightweight & Fast Linux Distros

  • Linux Bodhi
  • Linux Puppy
  • antiX
  • Slax
  • LXLE
  • SliTaz

Lightweight & Fast Linux Distros

Considered as a top-notch lightweight Linux Distros, Linux Bodhi is a life-saver for all the old laptops and computers who had been facing the threat of being discarded in no time due to their apparent uselessness. 

Linux Bodhi is specifically preferred for its minimalistic approach, therefore the lightweight feature is incorporated by avoiding unnecessary fancies, and involving those types of hardware applications that are rather old effectively. Its additional composition of Moksha Desktop improves its accessibility and performance further to a stellar state. 

The minimum hardware requirements for indulging with Linux Bodhi are 256 MB RAM, 1.00 GHz CPU as well as 5 GB disk space.

Built from the bits and pieces of packages of Ubuntu distros, Linux Puppy stands as one of the smallest Linux Distros with barely 300 MB space. Therefore, it solves the worry of many who were fearing to get their computer or PCs dumped with additional unnecessary storage for installing a big operating system along with the possible alterations it could bring. Indeed working like a small puppy occupying less space and being as much useful as possible.

You can choose any of the two variants broadly categorised into 32-bit and 64-bit that run on those PCs with UEFI and BIOS switched on. The minimum requirements for Linux Puppy to run on an old PC are again minimal than ever needing only a 600MHz processor and requiring only 256MB RAM.

AntiX has made itself suitable to sit with both earlier and newer versions of the machines by sharing comparable 32-bit and 64-bit variations. When the Debian-based system comes to the rescue for all types of obsolete PCs, antiX comes into action. Its ISO file, on the other hand, is 700 MB in size and may be downloaded and installed provided you have an adequate internet connection. 

For the first installs to begin and operate, the minimal requirements, which are also typical with other Linux Distros, are a 256 MB RAM, P III CPU system, and 5 GB disk space. AntiX, interestingly, makes use of the vanilla window manager, which can work on even the most basic PCs.

Slax is a one-of-a-kind film that retells how contemporary technology has grown to accommodate earlier computer systems so effectively. Its 32-bit and 64-bit versions are both portable and come with pre-installed apps. It is based on Debian and receives frequent upgrades. 

However, it has the drawback of not being able to connect to computers that are too old or too low-end. It has the tendency to prefer and feel stronger affinity for at least an i686 or the most recent CPU available. Then it requires a minimum of 128 MB RAM for desktop use and 512 MB for web-based use. Either the CD or USB disk may be used to boot the operating system. 

Lightweight & Fast Linux Distros

LXLE may seem to all Lubuntu fans to be pretty similar, since the features of Lubuntu and LXLE are quite similar, and LXLE may be considered the updated version of LXLE. The key benefit of LXLE is that users may not notice a loss of Lubuntu due to the inclusion of Lubuntu with more extra functionality. It can operate on previous versions with ease, and it was created with low-end PCs in mind. 

The minimal requirements for LXLE to function on older machines, or any kind of desktop or PC, may seem unusual, since it needs 1 GB RAM, a Pentium 3 CPU, and 8 GB of disk space, all of which are necessary for LXLE to be loaded. 

Lightweight & Fast Linux Distros

SliTaz is the lightest of all Linux Distros available on the market, consisting of an ISO file with a file size of roughly 40 MB that is capable of operating a full-fledged functioning unit in order to operate smoothly over the computer. It just need 100 MB of free space to get started. 

SliTaz’s minimum requirements are also significantly lower than anticipated; it just requires a Pentium III CPU and 256MB of RAM to run. It truly only uses 60 Mb for whatever action it does. As a result, it’s a win-win situation at a reasonable price.


To be more technical, Linux Distros are not fully functional operating systems like Windows, Mac, or Linux Kernel. Instead, it’s better described as a ‘usable’ or ‘provisional’ operating system that’s simple to install and uninstall applications on. As a result, they are popular due to their low cost; Linux is simpler to operate on older or reconditioned machines. As a result, businesses are no longer need to invest in the ongoing expenditures of purchasing new systems when the old one fails. Linux Distros also have a basic user interface that is straightforward to use.
