The hkuxzr micro firewall appliance alternatives list helps you find similar hardware for your network needs. You might look for other options if you need more ports, a faster processor, or a different brand. The original HKUXZR J5005 model offers four 2.5GbE ports and a fanless design for silent operation. It uses an Intel Celeron J5005 processor and comes as a barebone system, meaning you must add RAM and storage yourself. This setup suits users who want a quiet, compact device for custom routing software like pfSense or OPNsense.

We selected these 6 alternatives because their specifications overlap with the original unit. Each option provides barebone flexibility and 2.5G networking capabilities. Some models offer more LAN ports for complex home lab setups. Others feature newer processors like the Intel N100 or Core i3 for higher throughput. You can choose based on your specific port density requirements or budget constraints. All listed devices maintain the fanless, silent operation that defines this category. This guide compares them strictly by their published specs to help you decide which hardware fits your network architecture best.

Our top pick: HKUXZR J5005 4x 2.5GbE Fanless Mini PC.

Comparing Alternative Firewall Mini PCs

UDPTCP Celeron N5105 Barebone Firewall Mini PC

The UDPTCP Celeron N5105 offers a more modern quad-core processor compared to the HKUXZR J5005 dual-core. Both units are fanless and feature four 2.5GbE ports, making them suitable for similar silent routing tasks. The N5105 provides better single-thread performance for handling complex firewall rules or virtual machines. You get the same barebone flexibility, meaning you must supply your own RAM and SSD. Choose this model if you want slightly stronger processing power while maintaining the same compact, noise-free form factor and network interface count as the original.

VNOPN J3710 Fanless Firewall Mini PC

The VNOPN J3710 uses an older quad-core processor that is less powerful than the HKUXZR J5005. It retains the fanless design and four 2.5GbE ports, ensuring silent operation for basic routing needs. This unit is smaller in height, measuring 1.46 inches versus 1.69 inches, which helps in tight mounting spaces. You sacrifice processing speed for a lower price point and compact size. Pick this alternative if your network traffic is light and you prioritize physical size and cost over raw computational throughput for advanced network services.

Protectli Vault 4-Port Fanless Mini PC

The Protectli Vault FW4B is a well-known brand in the firewall space, offering a similar four-port 2.5GbE layout and fanless cooling. It uses an older Celeron processor, which may be slower than the HKUXZR J5005 in modern workloads. The chassis is slightly smaller in width and length, measuring 4.3 by 4.5 inches. It remains a barebone unit requiring separate RAM and storage. Select this option if you prefer established brand support and a proven track record for reliability, accepting potentially older internal components for a trusted ecosystem.

Glovary N150 6-Port Firewall Mini PC

The Glovary N150 steps up to an Intel N100 processor and includes six 2.5GbE ports instead of four. This provides greater network flexibility for complex homelab setups requiring multiple segmented networks. It also supports DDR5 memory, which is faster than the DDR4 found in the HKUXZR model. The chassis is larger and heavier, measuring 7.09 inches in length. Choose this unit if you need more physical network interfaces and modern memory standards, accepting a bigger footprint and higher cost for enhanced routing capabilities.

Glovary J6413 Fanless Firewall Mini PC

The Glovary J6413 features a J6413 processor, which is more powerful than the HKUXZR J5005. It maintains the four 2.5GbE port configuration and fanless design for quiet operation. This model is ideal for users who need better multi-core performance for virtualization or heavy packet inspection. Like the original, it is a barebone system requiring you to install RAM and storage. Opt for this alternative if you want a significant performance boost while keeping the same network port count and silent, compact form factor.

UDPTCP Core i3 6-Port 2.5GbE Firewall Mini PC

The UDPTCP i3-1215U model offers a modern Core i3 processor with DDR5 memory support, outperforming the HKUXZR J5005 significantly. It provides six 2.5GbE ports, offering higher density for advanced network segmentation. The unit is larger and heavier, weighing 4.5 pounds. It is designed for users who need substantial processing power and modern memory speeds for demanding firewall tasks. Select this option if you prioritize raw performance and port density over the smaller size and older technology found in the original barebone appliance.
