Build your own server by determining the purpose of the item and your long-term scaling plan and then purchasing the chassis, motherboard, CPU, hard drive and other components and installing them. After ensuring that all the components are compatible, connect the system to a dedicated power supply and Internet connection and then install a copy of the server operating system.
The process for building a custom server from scratch involves an extensive amount of research into various components to ensure not only compatibility but to ensure the server has the proper configuration and features for its intended purpose. For example, a server that simulates a virtual computer environment may need a faster processor and more memory compared to a unit that is going to primarily store data, which might call for a focus on hard drive space. Understanding the purpose of the server also allows you to create an initial list of parts, which you can use to identify a key component to use as the starting point.
Once you pick a single part as the basis for the server, you need to check all additional parts to ensure compatibility in design and function. After ordering the parts, start with setting up the chassis and installing the motherboard. Install the remaining components and follow their instructions to ensure proper handling and conduct the appropriate tests. Finally, choose the server operating system you wish to use, such as Linux, and install it to complete the testing process.
