The information below is intended to be helpful for customers who wish to learn more about enclosure design. Also, please use our online support if you have questions for our expert design staff. If you’re looking to integrate a standard form factor motherboard into your custom enclosure, the common ATX motherboard is universal, powerful, and cost-effective. Also, micro-ATX and mini-ITX motherboards have been developed specifically for applications where small size, low power consumption and minimal noise is desired. Many of the concepts in this resource also apply when designing enclosures for other motherboard form factors and custom built circuit boards as well. O connectors are accessed through the rear of the enclosure. However, if you choose alternate orientations, the same principles and details can be adapted.
O connector block locations are standardized on all ATX, Micro-ATX and mini-ITX motherboards. Clearances between the edges of the motherboard, fans, components, drives, cables, etc. Adequate ventilation must be designed into the enclosure to avoid component overheating. PCI Cards, are given relative to an origin on the corner of the motherboard. These must be offset correctly when transferred to your enclosure design. Key factors such as the desired offset of the board from inside surfaces, thickness of enclosure walls, and height of standoffs, must be considered. O board edge is typically placed 0.
O plate adaptor and the PCI card brackets. 020″ between PCI bracket and inside enclosure wall. It is possible to use smaller clearances for these sides however if you do – consider possible interferences between the board and enclosure details such as flanges, fasteners, and bend radii. Some PCI cards are longer than the example used in the motherboard images below, keep this in mind when designing your case. If using smaller clearances, be sure to discuss this with your account manager or technical representative, depending on which stage you are in your design. Standard motherboard mounting holes will accept a 6-32 thread size.
Figure 4 – Minimum offsets from bottom panel of an enclosure. Allow a minimum of 0. In the image above we allow . If you intend to use a fan-cooled processor in a situation with little clearance between the fan and the enclosure wall, we recommend fans that pull air directionally across the processor heat sink rather than down onto the top of the sink. Consider the orientation of fans carefully. Align intake and exhaust outlets so you can take advantage of the current they create, and make sure they don’t conflict with heat sink fan flow.
