2.4.3 Secondary (Bottom/Solder) Side Height Constraints
No height restraints on secondary side are added or removed from what is specified in
the microATX Motherboard Interface Specification.
2.4.4 Thin Mini-ITX System Considerations
While the low profile design of a Thin Mini-ITX motherboard creates the opportunity
for smaller PCs, system space must be allowed for factors such as airflow and cabling.
Board headers and the cable connectors they mate to should be selected with size and
orientation in mind. The use of tall headers which are perpendicular to the
motherboard and/or long cable connectors increase the chance of interference with
chassis components immediately over a Thin Mini-ITX board.
System integration challenges can be addressed in a variety of ways, including:
