Who it fits

Key specs explained for this firewall PC

Processor: Intel Celeron N5105

This quad-core chip runs at up to 2.9GHz. It provides enough power for routing tasks and light virtualization. You get efficient performance without generating excessive heat. This makes it suitable for always-on appliances where energy use matters. Compare this to faster desktop CPUs if you need heavy processing, but this unit is optimized for network duties rather than raw compute speed.

Ethernet Ports: 4x 2.5GbE

The device includes four Intel I226 network interfaces. Each port supports speeds up to 2.5 Gigabits per second. This allows you to connect multiple high-speed networks, such as separating WAN and LAN traffic. You benefit from higher throughput than standard 1GbE ports. When shopping, check if your router and cables support 2.5GbE to utilize this full capacity.

Installed RAM: 8GB DDR4

The system comes with 8GB of non-ECC DDR4 memory. This amount is sufficient for running firewall software and basic services. The listing notes support for up to 32GB via two slots. You can upgrade this later if you plan to run multiple virtual machines. Ensure you compare this against other mini PCs if you require more memory for complex home lab projects.

Storage Capacity: 128GB SSD

You receive a 128GB NVMe SSD for the operating system and logs. This provides fast boot times and quick data access. The unit also has slots for additional SATA or M.2 drives. You can expand storage easily if your firewall generates large logs. Check the available drive bays if you need significant space for file sharing or media servers alongside your network tasks.

Operating System: Linux

The appliance ships with a Linux environment, typically compatible with pfSense, OPNsense, or Proxmox. You must install your preferred firewall or hypervisor software yourself. This offers flexibility for advanced users who want full control. It is not a ready-to-use consumer OS like Windows. Verify your chosen software is supported before relying on this hardware for critical network security.

Fanless chassis and physical layout

According to the listing, this unit measures 6.1 inches in length, 5.31 inches in width, and 2.09 inches in height. It weighs 1.76 pounds. The compact dimensions allow it to fit into tight spaces, such as behind a monitor or inside a network rack. The small footprint is ideal for users who need a dedicated firewall without taking up much desk space.

The design is fanless, which means it operates silently. This lack of moving parts reduces dust accumulation and potential points of failure. You get a reliable appliance that runs quietly in a home office or server closet. The quiet operation is a practical benefit for environments where noise matters.

The build focuses on functionality rather than flashy aesthetics. It includes four 2.5GbE ports for robust network connectivity. Storage options include an M.2 NVMe slot and a 2.5-inch SATA bay, allowing you to expand capacity as needed. The layout supports easy installation of additional RAM or drives. This flexibility lets you tailor the hardware to your specific routing or virtualization needs without worrying about physical constraints.

Setup and everyday use

Setting up this appliance requires installing a supported operating system. The listing suggests pfSense, OPNsense, OpenWrt, or ESXi. You must ensure driver compatibility, particularly for the four Intel I226 network interfaces. The system supports auto power on and Wake-on-LAN, which helps in remote management. You do not need a monitor for daily routing tasks. However, the unit includes HDMI 2.0, DisplayPort 1.4, and a USB Type-C port. These allow you to connect up to three displays at 4K resolution if needed for local configuration. The fanless design means the device runs silently. This is practical for office environments or home labs where noise matters. The Celeron N5105 processor handles routing logic efficiently. You can expect stable performance for firewall duties. Storage expansion is flexible. You have an M.2 NVMe slot, a 2.5-inch SATA bay, and a secondary M.2 2230 slot for Wi-Fi or additional storage. The included 8GB RAM and 128GB SSD provide a baseline configuration. You can upgrade to 32GB RAM using dual DDR4 slots. This allows for more complex virtualization setups. The unit supports AES-NI encryption, which accelerates secure tunneling. Daily use involves monitoring network traffic and managing rules. The watchdog feature helps maintain uptime. You should check for BIOS updates via the seller for optimal stability. The compact size allows mounting behind a monitor or in a rack. This makes integration into existing network infrastructure straightforward.

Before You Buy This Firewall PC

Before you buy this MOGINSOK appliance, verify your network infrastructure supports 2.5GbE speeds. You need compatible cables and switches to utilize the four Intel I226 ports effectively. Check that your chosen operating system, such as pfSense or OPNsense, has stable drivers for these specific NICs. The listing notes that driver compatibility is crucial for performance. Since the unit is fanless, ensure you have adequate ventilation in your setup location. You may need additional storage if the included 128GB SSD fills up with logs. This micro PC fits well alongside other small form factor computers in Mini PCs & Small Form Factor Computers for users prioritizing quiet, dedicated networking hardware. It is not a general-purpose desktop replacement. You should plan for its specific role as a firewall or router. Consider whether your current network setup can benefit from the increased bandwidth. Proper cable management will help maintain the compact footprint. Regular BIOS updates from the manufacturer may improve stability. This appliance suits technical users who understand Linux-based networking environments.

Check before you buy

• Verify your switches support 2.5GbE speeds.
• Confirm OS driver compatibility for I226 NICs.
• Ensure adequate ventilation for the fanless design.
• Check if you need extra storage capacity.
