How alternatives compare to VNOPN
Sharevdi Fanless 2.5GbE J4105 Firewall Mini PC
The Sharevdi J4105 model uses a faster Intel J4105 processor compared to the VNOPN J3710, offering better single-core performance for network tasks. It retains four 2.5GbE ports and 8GB of RAM with a 240GB SSD, matching the original’s storage and memory configuration. The main difference is form factor; this unit is taller and heavier, measuring 6.3 inches in height versus 1.4 inches. You get silent operation and VESA mounting compatibility in both. Choose this if you need more CPU power while keeping the same port density and storage capacity.
VNOPN Fanless 4-Port Firewall Mini PC
This VNOPN alternative uses the same J3710 processor and 8GB RAM but reduces storage to a 128GB SSD. It keeps the four 2.5GbE ports and fanless design identical to the original. The chassis dimensions are nearly the same, ensuring it fits in similar spaces. You sacrifice double the storage capacity for a lower entry point. This model suits users who do not need large local storage for logs or virtual machines. It is the practical choice if you prefer the original’s hardware but want to minimize disk space usage and cost.
Glovary Fanless Quad-LAN Mini PC
The Glovary J4125 model offers four Gigabit Ethernet ports instead of the original’s 2.5GbE ports, meaning lower maximum network throughput. It uses a J4125 processor, which is generally more efficient than the J3710. Storage is reduced to 128GB SSD with 8GB RAM. The chassis is larger and thicker at 2.17 inches high. You gain industrial durability and potentially better power efficiency. Pick this if your network infrastructure relies on standard Gigabit connections and you need a more robust industrial build rather than high-speed 2.5G connectivity.
Sharevdi Fanless Firewall Mini PC Intel 6006U
This Sharevdi unit significantly upgrades networking with six 2.5GbE ports compared to the original’s four. It uses a modern Intel 6006U processor, providing much higher performance than the J3710. Storage remains at 240GB SSD with 8GB RAM. The chassis is larger, measuring 7 inches in length. You get more LAN interfaces and better CPU speed for complex routing tasks. Choose this if you need extra network ports for multiple interfaces or require stronger processing power for advanced firewall rules and virtualization in a silent, fanless design.
Glovary N150 6-Port Fanless Mini PC
The Glovary N150 model features six 2.5GbE ports, offering greater network density than the original’s four ports. It uses an Intel N100 processor, which is significantly faster and more efficient than the J3710. Storage is slightly larger at 256GB SSD with 8GB RAM. The chassis is taller at 2.17 inches. You gain modern DDR5 memory support and superior CPU performance for heavy workloads. Select this if you need maximum port density and modern processing power for a high-performance soft router or firewall setup.
Thdeukoty Fanless Core i7 Industrial Mini PC
The Thdeukoty i7-5500U model provides dual LAN ports instead of the original’s four, reducing network interface count. It uses an older Intel Core i7 processor, which may offer different performance characteristics but lacks modern efficiency. Storage is limited to 128GB SSD with 8GB RAM. The chassis size is not fully specified but appears compact. You trade network port quantity for a dual-core i7 architecture. This option suits users who prioritize a specific processor lineage or need fewer network interfaces for a simpler, dual-network home lab configuration.
