CALCULATION BASIS
Mechanical Envelope and Clearance Model
The checker treats the board, enclosure, connector projection, component stack, and selected design clearance as simple geometric envelopes.
Footprint Requirement
Required width = board width + 2 x clearanceDepth also includes the entered connector or cable projection beyond the board edge.
Top Clearance
Top gap = enclosure height - standoff - PCB - top stackThe result is compared with the selected design clearance above the tallest component.
Bottom Clearance
Bottom gap = standoff height - underside stackUse the actual underside component height and finished standoff height.
Expansion Length
Card margin = available length - installed card lengthThis optional check does not validate slot alignment, card thickness, or cable interference.
INPUT QUALITY
Use Finished Mechanical Dimensions
Nominal case size and marketing labels are not enough for enclosure integration.
Internal Enclosure Size
Measure usable internal width, depth, and height after brackets, ribs, filters, and wall thickness are included.
Component Stack
Use the tallest installed heatsink, memory, connector, cable bend, and underside component—not the bare board height.
Connector Projection
Include internal cable bend radius and connector bodies that extend beyond the nominal board outline.
Manufacturing Margin
Add clearance for tolerance, assembly access, vibration, insulation, airflow, and serviceability.
ENGINEERING BOUNDARY
What the Checker Includes and What CAD Must Verify
Included in the Screening Check
- Mini-ITX 170 x 170 mm board outline
- Custom board dimensions
- Enclosure footprint and z-height
- Top and underside component clearance
- Connector projection and optional card length
Verify in Mechanical CAD
- Mounting-hole coordinates and fastener access
- Rear I/O shield and panel cutouts
- PCIe slot alignment and card thickness
- Cable routing, bend radius, and strain relief
- Airflow, fan, heatsink, and service clearances
GEOMETRY SCREENING IS NOT A RELEASE DRAWING
Use the result to identify obvious fit risks, then validate the actual assembly in CAD and with a physical prototype.

Practical Questions Before Enclosure Release
Use the checker for early envelope screening, then confirm every interface from the product drawing.
The answers focus on board size, z-height, connector projection, and expansion-card fit.
Discuss a Mechanical Integration RequirementWhat is the standard Mini-ITX board size?
A standard Mini-ITX motherboard uses a nominal 170 x 170 mm board outline. Always verify the exact product mechanical drawing.
Does a 170 x 170 mm enclosure automatically fit Mini-ITX?
No. The enclosure needs additional space for standoffs, wall thickness, I/O, cables, components, tolerances, and assembly access.
How much clearance should I leave around the board?
Use the product and manufacturing requirements. A few millimeters may be adequate for screening, but connectors, airflow, insulation, and service access can require more.
Does this tool verify Mini-ITX mounting holes?
No. It checks envelopes only. Confirm mounting-hole coordinates, fastener diameter, standoff position, and rear I/O alignment from the board drawing.
How should I enter cable clearance?
Enter the internal connector body and cable bend projection beyond the board edge, including strain relief and assembly tolerance.
Can this replace a CAD interference check?
No. It is a fast screening tool. Final release requires detailed CAD, actual component models, panel drawings, and prototype fit verification.
