Firewall Mini PC Quad Core N150 - Fanless 6x 2.5GbE Micro Router

In this review of the Firewall Mini PC Quad Core N150, the bottom line is clear: this compact appliance is aimed at small offices, home labs and network enthusiasts who need multiple fast Ethernet ports and flexible OS support. The biggest reason to buy is the combination of a lowpower Twin LakeN N150 processor with six i226V 2.5GbE ports, which makes it well suited as a dedicated firewall or router platform running OPNsense or other open router software. It is a practical, fanless box with expandability for NVMe and SATA storage for persistent logs and packages.

Key Features

• Processor: The Twin LakeN 12th Gen N150 with 4 cores and up to 3.6 GHz delivers efficient packet processing for firewall and routing tasks while keeping power consumption low.
• Multiport Networking: Six i226V 2.5GbE LAN ports provide aggregated bandwidth and multiple interface segmentation that is 2.5x faster than standard gigabit for demanding LAN setups.
• Memory and Storage: A single DDR5 SODIMM slot and dual M.2 NVMe slots plus SATA 3.0 support allow for fast memory and large, bootable storage capacity for logs, caching and virtual appliances.
• Fanless + Optional Fan: The aluminium alloy body enables quiet operation for desk placement while an optional 12V 4pin small fan can be added if cooling is required under sustained load.
• Display & Ports: Integrated UHD graphics drive triple displays via 2x HDMI and TypeC at up to 4K@60Hz, useful for local management or monitoring consoles.
• OS Flexibility: Broad platform support for OPNsense, Linux, ESXi and OpenWrt means it can serve as a dedicated firewall, hypervisor host for small VMs, or embedded router.

Who It's For

The Firewall Mini PC is best for small businesses, home lab users and network enthusiasts who need multiple physical ports and the ability to run OPNsense or other router OS images natively. It is a solid choice when you require a compact, fanless appliance that still offers NVMe storage, DDR5 memory and triple display outputs for local consoles.

Users who rely on advanced vendor support or require enterprise warranties, very high port densities beyond six 2.5GbE ports, or perfectly silent operation under sustained maximum load should consider other purposebuilt appliances or chassis solutions with active cooling and larger support contracts.

Pros & Cons

Pros

• Excellent build quality and stable operation reported by multiple users for continuous firewall duty.
• Six 2.5GbE ports give real upgrade headroom over gigabit networks for LAN segmentation and throughput.
• Flexible storage and memory expansion with DDR5, dual M.2 NVMe and SATA make it adaptable to many roles.
• Fanless aluminium case keeps noise down for desktop or rack use, with an optional small fan cable if extra cooling is needed.

Cons

• Some customers report mixed results with specific features such as VLAN behavior under certain OS configurations, so testing in your environment is advised.
• The unit can run warm under load; while fanless design is quiet, added cooling may be needed for sustained heavy traffic.

Specifications

Our Verdict
