Hi!

I have an old PC lying around with a 2.6GHz Pentium 4 and 512MB RAM. What good lightweight linux distros would work with it?What is the best Linux Distro for an old PC?
Your machine looking at the specs. will run Linux well although you may want to consider increasing the RAM to 1gb



I thoroughly recommend Linux Mint 9 LTS which is built upon Ubuntu 10.04 LTS its easy to install and easy to use plus it comes with much of the software you are likely to need preinstalled

You download the ISO. image of Linux Mint 9 LTS then you need to create a Bootable LiveCD for installation

Linux Mint 9 LTS can also be run direct from the LiveCD from Boot without touching your Hard Drive



Once you have installed Linux Mint 9 LTS you can bring it up to date with easy tweaks like upgrading the Kernel to 2.6.38 and installing Firefox 4
