Mounting & usage guide

Mounting

Footprint 196 × 189 mm, 48 mm tall (about 1.78 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 130 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.
