Low cost Raspberry pi Cluster (with 24 pin motherboard power supply)

When people try to save money by creating a Raspberry Pi cluster, they often face the challenge of not only needing the Raspberry Pi itself, but also having to purchase additional components such as a USB-C cable, a USB power hub, a 4-port switch, and a cluster case. These items can add up and increase the overall cost of building a cluster.

On average, a USB-C cable can cost around $10, a USB power hub around $20, a 4-port switch around $25, and a cluster case around $40. However, there is a way to save some money and reduce the cost of building a cluster.

Instead of purchasing all of these components, you can use an old 24-pin computer power supply and connect it directly to the 5V port on your Raspberry Pi, also, instead of use a 4-port switch to connect to the internet, use the embedded wi-fi. This not only saves you money, but also helps to reduce electronic waste.

To create a cluster using this method, you will only need a 24-pin power supply, a switcher (optional), and a Raspberry Pi cluster case, in this project we added a fan too and a py code to control turn it on when the cpu fan reaches a target degree. The connection diagram for this setup is shown below, making it easy for anyone to create their own Raspberry Pi cluster without breaking the bank.

So, with just a few simple steps, you can build your own Raspberry Pi cluster and save money in the process!

This is the final result of my cluster, in this project I saved at least $100 on my savings!
