Figure 5. Mini-ITX Maximum Component Height Restrictions
Notes:
 All dimensions in the above figure are in millimeters (mm).
 The 57mm height restriction in Area A applies to the PC board component height.
The actual height of the chassis should include any dynamic excursion
considerations for shipping as well as needs to facilitate alternative cooling
solutions or airflow considerations.
 For the Intel boxed processor fan heat sink, it is strongly recommended not to
place components between fan inlet and chassis side vent by leaving space
between chassis wall and area A open.
 The component height requirement assumes a motherboard thickness of 1.57 mm
(.062”).

Constraints
Figure 6 shows the required Thin Mini-ITX volumetric envelope for the PCB and all
motherboard components. For full compliance with Thin Mini-ITX, and to prevent
