Linux is great for a litany of reasons, but one of the most important is refurbishing. You see, an operating system based on the open-source kernel can breathe new life into an older computer, and effectively turn it into a new machine. This is because the operating systems are typically less system intensive than Windows.
Unfortunately, not all Linux-based operating systems are equally lightweight. Some may require better specs than others, usually due to the environment. Something like Unity or KDE may require a more modern computer for an optimal experience, but what if your machine has really low specs? A great environment for an old and weak machine is Xfce. Though not the lightest, it feels modern, while lighter environments can feel archaic. Today, Linux Mint embraces the low-end, with version 17 of its operating system, now with Xfce as an option.
