Most Mini PCs today are designed for office workloads, media playback or lightweight desktop environments.
But recently, more x86 systems are starting to target a completely different area:
- pfSense
- OPNsense
- Multi-WAN routing
- Industrial networking
- Network security
- Edge computing
- SD-WAN
One of the more interesting designs I came across recently is a fanless x86 platform with a total of 16 Ethernet interfaces.
The system combines:
- 8× Intel I225/I226 2.5GbE ports
- 8× Gigabit Ethernet ports
which already makes it feel much closer to a lightweight network appliance than a traditional Mini PC.
Front I/O Layout
The front panel includes:
- 2× USB 3.0
- 2× USB 2.0
- HDMI
- DisplayPort
- RS-232 console port
- Power / Reset buttons
The HDMI and DP outputs are useful for local installation and debugging, especially for:
- pfSense
- OPNsense
- OpenWRT x86
- Linux firewall environments
The RS-232 interface also makes more sense in industrial deployments where serial communication is still common.
CPU and Expansion Options
The platform supports several low-power Intel U-series processors, including:
- Whiskey Lake-U
- Coffee Lake-U
- Comet Lake-U
Depending on the configuration, the system can scale from low-power Celeron processors up to Core i7 models.
Memory support includes:
- DDR4 SO-DIMM
- Up to 32GB RAM
Storage support includes:
- 2.5-inch SATA SSD/HDD
- mSATA SSD support
The motherboard also provides:
- Mini PCIe expansion
- SIM slot
- Wi-Fi / 4G module support
which makes the platform more flexible for edge deployments and remote networking environments.
Why 16 Ethernet Ports?
This is the part that makes the platform interesting.
Most firewall appliances stop at:
- 4 ports
- 6 ports
- maybe 8 ports
but once industrial or segmented networking environments become more complex, port count starts becoming more important.
For example:
- PLC networks
- SCADA systems
- Cameras
- MES systems
- IoT devices
- NAS traffic
- Office traffic
- VPN traffic
are often separated into dedicated network segments.
While VLANs can technically handle this, many industrial environments still prefer physical separation because troubleshooting and maintenance become much easier later.
A dedicated interface per segment is easier to document, easier to isolate and often easier for long-term operation teams to maintain.
Intel NICs and pfSense Compatibility
The 8 Intel I225/I226 2.5GbE ports are especially interesting for:
- pfSense
- OPNsense
- BSD networking
- Multi-WAN
- VPN gateways
Intel NICs generally have better driver support and more stable behavior under BSD-based firewall systems compared with many consumer Realtek solutions.
Fanless Design for Always-On Deployments
The entire chassis uses a passive cooling design.
For networking appliances running:
- 24/7
- inside cabinets
- in dusty environments
- in industrial control rooms
fanless hardware still makes a lot of sense.
Less dust accumulation.
Less moving parts.
Less maintenance over time.
Final Thoughts
What I find most interesting is how these systems are slowly evolving away from the idea of a “Mini PC”.
They are becoming compact x86 infrastructure platforms.
Especially for:
- pfSense labs
- HomeLab networking
- Industrial segmentation
- VPN routing
- SD-WAN testing
- Edge gateway deployments
higher port-count fanless systems are starting to make more practical sense than they did a few years ago.
Honestly curious how many people here are still using physical network isolation instead of relying entirely on VLAN segmentation.
