mounting screws are not supplied with the motherboard. The chassis
manufacturer should supply these parts.

damage during installation. Connect an alligator clip with a wire lead to any
unpainted part of the chassis. Ground the other end of the lead at the same point as
the mat and the wristband.
2 Rotate the chassis so the front is to the right, and the rear is to the left. The side facing
you is where the motherboard is mounted. The power supply is mounted at the far end
of the chassis.
3 Hold the motherboard, component-side up, with the edge with the SIMM sockets
toward you and the edge with the power supply connector away from you. The
keyboard, mouse, and video connectors should be to the left.
4 Carefully slide the motherboard into the chassis. Make certain the edge connectors fit
the ports in the rear of the chassis. The motherboard should rest level with the
chassis.
