Mounting & usage guide

Mounting

Footprint 185 × 150 mm, 40 mm tall (about 1.11 litres).
Supports VESA mounting: fix it to a wall or under a shelf near your modem and switch, with the network ports facing down or sideways for easier cabling.
When VESA-mounted, keep the vents clear: leave at least 1-2 cm between the case and the monitor.

Cooling & heat

Fanless aluminium case: the chassis is the heatsink and can feel hot to the touch in continuous use, which is normal.
Avoid closed cabinets without airflow; when lying flat, leave a few cm above the fins.
Clean dust from the vents every 6-12 months to keep temperatures and power draw low.

Recommended use cases

OPNsense or pfSense firewall/router: 5x 1GbE to split WAN, LAN and VLANs.
Always-on Home Assistant: at about 10 W idle it is cheap to run 24/7.
Proxmox VE with several VMs and LXC containers: up to 32 GB RAM.
