Specifications side by side

Protectli Mini PC Specs Overview

Protectli designs fanless mini PCs for silent network security. These units prioritize dedicated hardware for firewall tasks over general computing. You choose between basic routing or high-density port configurations. The lineup focuses on compact form factors that fit easily into tight spaces.

The FW4B offers four ports for standard home gateways. It includes 4GB RAM and a 32GB SSD. The FW4C adds 2.5G LAN support for faster local traffic. The FW2B provides two ports for simpler setups. Each model runs quietly without moving parts. Select the option that matches your port count needs.

Who Protectli Fits Best

Protectli targets users who need silent, dedicated network hardware. The range spans from basic two-port models to four-port units with higher-density connectivity. All listed devices share identical physical dimensions, roughly 4.5 by 4.3 by 1.5 inches. They offer black chassis options and fanless cooling for zero noise. Each unit provides 4GB of RAM and 32GB of storage. You will not find larger cases or high-performance computing options here. This brand suits those prioritizing network port count and silence over raw processing power or expandability.

How to Choose a Protectli Mini PC

1. Match Ports to Network Needs

   Check the number and speed of LAN ports before buying. The Protectli Vault 4-Port 2.5G Mini PC offers four high-speed 2.5G connections, ideal for users with multiple gigabit devices or high-bandwidth internet plans. In contrast, the 2-Port Fanless Mini PC provides only two standard ports, which suits basic home networking. Ensure the port count matches your router and switch requirements. More ports allow for dedicated connections to different network segments or devices without needing external adapters.

2. Consider RAM for Firewall Tasks

   All listed Protectli models come with 4GB of RAM. This amount is sufficient for standard firewall and routing duties, such as running pfSense or OPNsense. You do not need more memory for basic network security tasks. However, if you plan to run additional services like ad-blocking or lightweight virtual machines, 4GB may become a bottleneck. For most users acting solely as a network gateway, this memory level is adequate. Do not expect to use these units for heavy desktop computing due to this fixed specification.

3. Evaluate SSD Capacity for Logs

   Storage size affects how long you can keep system logs and configurations. Each model includes a 32GB SSD, which is small but functional for firewall software. You must ensure your chosen operating system fits within this limit, as network OS images can be large. If you enable extensive logging features, the drive may fill up faster. Consider external storage options if you need to retain detailed network traffic records for compliance. For simple routing tasks, the internal SSD provides enough space for the OS and essential updates.

4. Prioritize Silent Fanless Operation

   All Protectli units in this list are fanless, meaning they generate no noise. This makes them suitable for placement in living rooms or offices where silence is important. The passive cooling design relies on heat dissipation through the chassis. Ensure you have adequate airflow around the device, as there is no fan to push air through. The compact dimensions, roughly 4.5 by 4.3 by 1.5 inches, allow them to fit in tight spaces. This feature is a primary advantage over traditional tower PCs that use noisy fans.

5. Verify Form Factor for Mounting

   The small physical size allows for flexible installation. You can mount these units under desks or behind monitors using VESA mounts, provided you check the specific model dimensions. The Protectli Vault 4-Port Mini PC measures 4.56 by 4.25 by 1.69 inches. The FW4B model is slightly smaller at 4.3 by 4.5 by 1.5 inches. Verify your available space before purchasing. The low profile ensures they do not obstruct other equipment. This compact form factor is ideal for users who want a clean, unobtrusive setup in their home network.
