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.

Under load it reaches about 68 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.
