The BC1 Mini was designed to accommodate a MINI-ITX size motherboard but it can also be used with MINI-DTX motherboards.
Standoffs will need to be fitted to the 4 positions corresponding to the ITX motherboard standard mounting points.
Both pushpin and M3 screw type standoffs can be used depending on your requirement.
Install the Standoffs
Install either the pushpin or M3 standoffs in the appropriate motherboard mounting locations by hand tightening them.
Install the Motherboard
Ensure once again that the correct holes have been used for the standoffs, then lower the motherboard onto them.If using the pushpin standoffs, give a firm push until yo feel the motherboard ‘click’ into place.If using the M3 standoffs, M3 screws should be used to secure the motherboard to them.
