Mounting & usage guide
Mounting
- Footprint 117 × 112 mm, 37 mm tall (about 0.48 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 64 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
- 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 64 GB RAM.
- Heavy office work, light photo/video editing and intensive multitasking.
