Fanless design to reduce noise and enhance reliability.
Multiple Network Interface Card (NIC) slots for versatility.
Enough processing power to handle your network traffic without bottlenecks.
Proximity in size to standard routers for easy placement.

Ensure the SFF computer has a solid-state drive (SSD) for quick data access. RAM should be sufficient for running the routing software smoothly. Also, consider power efficiency as it will be on 24/7.

Choosing the Right Network Interface Card (NIC)

NICs are crucial as they connect your router to the network. Consider the following when choosing a NIC:

Compatibility with your chosen SFF and software.
Quality from reliable brands like Intel to ensure stable connections.
The number of ports depending on the size of your network.
Support for high speeds if you have gigabit internet.

Remember, a high-quality NIC can help achieve the desired speeds and reliable connectivity for your home network.

Selecting Router Software: Open Source vs Proprietary

When building your own router, the choice of software is crucial. You’ll find two main types: open source and proprietary. Open source software, like pfSense, OPNsense, and OpenWRT, is free and customizable. Proprietary software, on the other hand, often comes at a cost but can offer dedicated support and unique features. The decision hinges on whether you prioritize customization or convenience.

Getting Started with pfSense

Getting started with pfSense, a popular open source router software, requires some prep. First, verify your hardware meets pfSense requirements. Download the software from the pfSense website.
