Mounting & usage guide
Mounting
- Footprint 222 × 206 mm, 77 mm tall (about 3.52 litres).
- Supports VESA mounting (75/100 mm bracket): attach it behind your monitor or under the desk to free up space. Keep the front USB ports and power button reachable.
- When VESA-mounted, keep the vents clear: leave at least 1-2 cm between the case and the monitor.
Cooling & heat
- Under load it reaches about 78 W and the fan becomes audible. For an always-on server, lower the power limit (TDP) in the BIOS to cut heat and noise.
- Clean dust from the vents every 6-12 months to keep temperatures and power draw low.
Recommended use cases
- Virtualised router (OPNsense VM on Proxmox) using the 2x 10GbE.
- Always-on Home Assistant: at about 8 W idle it is cheap to run 24/7.
- Proxmox VE with several VMs and LXC containers: up to 128 GB RAM.
- Home lab with fast network storage: the 10G ports suit NAS, backups and Proxmox clusters.
- Heavy office work, light photo/video editing and intensive multitasking.
- Running local AI/LLM models thanks to the large unified memory.
