Firewall Mini PC Comparison
storage capacity
The VNOPN Fanless 4-Port Firewall Mini PC includes a 128GB mSATA SSD. This provides double the internal storage of the VNOPN Fanless Intel J3710 Mini PC, which comes with a 64GB mSATA SSD. Both units support upgrades up to 512GB, but neither supports HDD storage. For a firewall appliance, the larger base storage on the first unit offers more room for logs and system files without immediate upgrades. The second unit’s smaller drive may require earlier expansion for heavy logging environments.
network interfaces
Both models feature four Intel i226 2.5GbE LAN ports, ensuring identical high-speed networking capabilities for your network gateway setup. They also share two USB 3.0 ports. However, the VNOPN Fanless Intel J3710 Mini PC adds an RS232 COM port and two HD ports, while the 4-Port Firewall Mini PC lists one HDMI and one VGA port. The COM port on the second unit is useful for legacy serial console access, whereas the video outputs on the first unit allow for direct monitor connection.
power consumption
The VNOPN Fanless 4-Port Firewall Mini PC has a stated TDP of 6W. The VNOPN Fanless Intel J3710 Mini PC lists a TDP of 6.5W. Both are fanless and designed for 24/7 continuous operation with aluminum alloy chassis for heat dissipation. The difference is minimal, but the first unit consumes slightly less power under load. For always-on network appliances, every watt counts toward efficiency and heat generation in enclosed spaces.
physical dimensions
The dimensions are nearly identical between the two units. The VNOPN Fanless 4-Port Firewall Mini PC measures 5.27 x 4.98 x 1.43 inches. The VNOPN Fanless Intel J3710 Mini PC measures 5.27 x 4.98 x 1.43 inches according to its features, though its specs list a height of 1.43 inches and length of 5.27 inches. Both weigh approximately 500g. Both support VESA mounting for space-saving installation behind monitors or on walls.
operating system support
Both units are tested with pfSense, OPNsense, Ubuntu, and other popular open-source OS options. The VNOPN Fanless 4-Port Firewall Mini PC explicitly supports Proxmox VE for virtualization and home lab applications. The second unit mentions testing with similar OS but does not list Proxmox VE support. If you plan to run virtualization software alongside your firewall, the first unit’s explicit compatibility is a clear advantage for your home lab setup.
Which VNOPN Mini PC Suits You
Users needing more local storage
The VNOPN Fanless 4-Port Firewall Mini PC includes a 128GB mSATA SSD. This offers double the storage capacity compared to the 64GB model. If you plan to store logs, backups, or additional system files locally, this extra space is a practical advantage for your network appliance setup.
Users requiring RS232 serial connectivity
The VNOPN Fanless Intel J3710 Mini PC features an RS232 COM port. This serial interface is essential for connecting legacy industrial devices or specific network hardware. If your project relies on serial communication protocols, this specific port makes this model the necessary choice over the other option.
Users needing dual video outputs
The VNOPN Fanless Intel J3710 Mini PC lists two HD ports in its specifications. This allows you to connect two displays simultaneously. If you need a local visual interface for monitoring or configuration without relying on remote access, having dual video outputs provides greater flexibility for your workspace.
