With the standoffs fitted to the main body and after verifying the correct support locations have
been installed, carefully lower the motherboard onto the pushpin standoffs and with a slight
amount of pressure, force them through the motherboard holes. This will securely lock the
motherboard in place. Note that any CPU retention plates should be fitted prior to installing the
motherboard for ease of use. If using threaded standoffs to secure the motherboard, install the
M3 screws to lock the motherboard in place.
A total of 4 PCI support screw sets are supplied, and can be used individually or in pairs for dual
width cards as required.
PCI cards are secured to the BC1 using the PCI thumbscrews which should first be screwed into
the threaded standoffs fitted to the PCI support mounting holes. The PCI card can then be
installed into the motherboard slot ensuring the card mounting bracket hole aligns with the top
of the PCI thumbscrew. Finally screw the PCI nut to the top of the PCI screw to lock the card in
place.
