Expansion Card Support
The BC1 Mini has a total of 3 PCI support positions. When used with a Mini-ITX motherboard, this will allow a single, double or triple-slot card to be secured. With a Mini-DTX motherboard, a single + double slot card can be fitted.
Install Support Screws
Before fitting the expansion card, install the PCIe support screws. They must be installed in conjunction with M3 standoffs. Position and install the standoffs then screw the support screws into them. The nuts at the top of the screw should be removed before fitting the card.
Fit the Card
Lower the card onto the motherboard, alighting it with the socket and ensure the top of the support screw aligns with the mounting holes of the card.
Once the card is properly seated in the socket, use the M3 nuts to secure it to the PCIe support screws.
