Mounting & usage guide
Mounting
- Footprint 135 × 135 mm, 45 mm tall (about 0.82 litres).
- No VESA mount: place it on a shelf or a rack tray, or use a universal strap-style mini PC holder.
Cooling & heat
- Under load it reaches about 62 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 7 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.
