Do you have an old computer (laptop or desktop) sitting in your closet after purchasing a new computer? Even if your PC is no longer supported by the OS or is too slow to use on a daily basis, you can use it as a “home server” to enjoy a second life. This time, we will introduce the benefits and methods of reusing an old PC as a home server.
Advantages of using an old PC as a server First of all, you can start learning how to build a server at “zero cost.” Even if you fail, you can simply reinstall the OS, so you can learn Linux commands and network knowledge without worrying. Another big advantage of laptops is that they have a built-in battery, display, and keyboard. It continues to operate on battery power even during a power outage (replaces a simple UPS), and can be operated directly by looking at the screen even in the event of a problem, making it an excellent choice for server applications.
**What can it be used for? ** The uses are limitless depending on your ideas. ・File server (NAS): Save and share photos, videos, and backup data. ・Media server: Install Plex and other software to stream saved videos to smartphones and TVs. ・Minecraft multi-server: Launch a dedicated Minecraft server to play with friends. ・Test environment for development: Install Docker and use it as a learning and testing environment for programming.
How to get started It is common to erase (or dual-boot) Windows on an old PC and install a Linux distribution such as “Ubuntu Server”, which is a standard OS for server construction. The CUI environment, which does not have a GUI (graphical screen), is very light and runs smoothly even on PCs from 10 years ago.
An old PC that’s too good to throw away. Please revive it as a home server and experience the convenient and profound world of server operation.
