How alternatives compare to ZOTAC
Glovary N150 6-Port Firewall Mini PC
The Glovary N150 shares the Intel N100 processor and fanless cooling of the ZOTAC ZBOX CI337 Nano. It differs by offering six 2.5GbE LAN ports instead of two Gigabit ports. This makes it superior for home labs requiring high-speed networking. You give up the compact cubic shape for a longer chassis measuring 7.09 inches in length. The N150 is also a barebone system, so you must install your own RAM and SSD. Pick this alternative if your primary need is advanced routing or firewall capabilities with multiple high-speed Ethernet connections.
Glovary Barebone Fanless Firewall Mini PC
The Glovary J3710 Firewall Mini PC uses an older Intel Celeron J3710 processor, which is less powerful than the N100 in the ZOTAC unit. It provides multiple 2.5GbE ports for network-focused tasks. This model is larger and heavier than the ZOTAC ZBOX CI337 Nano. It lacks the modern connectivity features like WiFi 6. You should choose this barebone option if you are on a tight budget and need a dedicated, silent router. It is suitable for users who prioritize network port quantity over modern processing speed and wireless connectivity.
VNOPN J3710 Fanless Firewall Mini PC
The VNOPN J3710 Fanless Firewall Mini PC also relies on the older Intel Celeron J3710. It offers dedicated 2.5GbE ports for silent networking builds. The chassis is slightly larger than the ZOTAC ZBOX CI337 Nano but remains compact. This barebone unit requires you to add your own memory and storage. It lacks the integrated graphics performance and modern I/O of the N100. Select this alternative if you need a low-cost, silent firewall appliance. It is best for users who do not require high-performance computing or wireless networking features.
HEIGAOLAPC Fanless N100 4-Port Firewall Mini PC
The HEIGAOLAPC N100 Fanless Mini PC includes the same Intel N100 processor as the ZOTAC ZBOX CI337 Nano. It comes pre-installed with 8GB of RAM and a 128GB SSD, unlike the barebone ZOTAC. It features multiple 2.5GbE LAN ports for enhanced networking. However, it offers less storage expansion and fewer USB ports than the ZOTAC. You pick this unit if you want a ready-to-use device without buying components separately. It is ideal for users who need a silent, pre-configured firewall or router with moderate processing power.
Glovary J4125 Fanless Firewall Mini PC
The Glovary J4125 Fanless Firewall Mini PC uses an Intel Celeron J4125 processor, which is older than the N100 in the ZOTAC ZBOX CI337 Nano. It provides multiple Ethernet ports for industrial or home lab use. This barebone system requires you to install RAM and storage. It lacks modern wireless connectivity and advanced graphics capabilities. Choose this alternative if you need a rugged, silent networking device for specific routing tasks. It is suitable for users who prioritize Ethernet port quantity and low power consumption over modern processing performance.
AZULLE Access Pro Fanless PC Stick
The AZULLE Access Pro is a fanless stick PC with an Intel N100 processor. It is significantly smaller than the ZOTAC ZBOX CI337 Nano, measuring only 2 inches in width. It comes with 4GB of RAM and 64GB of eMMC storage. This unit is designed for digital signage or IoT displays rather than general desktop use. It lacks the expansion options and multiple LAN ports of the ZOTAC. Pick this alternative if you need the smallest possible form factor for a fixed installation.
