Although you don't need to install the motherboard baffle, the resulting large gap will allow a lot of dust to invade the inside of the chassis, which will affect the heat dissipation of the computer. If the baffle is barely placed at the rear opening of the chassis, the bent edge of the baffle will form a thickness of about 3cm, so that when installing the motherboard, the I/O interface of the motherboard cannot be aligned with the interface position of the baffle, and the motherboard is misplaced, and the installation screw hole cannot be aligned with the copper stud nut at the bottom of the chassis.
1, you can open the back of the chassis a little wider, but the metal plate there is thicker and inconvenient to operate, so the author thought of reforming the motherboard baffle. After all, its material is thinner, which is beneficial to bending. Clamp the edge bending part of the motherboard baffle flat with needle-nose pliers. Only one side near the PCI slot needs to be treated, and all three sides should be clamped flat.
2. Because a part of the extra metal block on the lower edge will be clamped flat and will be close to the bottom of the chassis, which will hinder the installation of the baffle, it needs to be bent and close to the bottom of the chassis. Don't worry about shorting the bottom of the motherboard, because the copper stud nut on the chassis has a certain height.
3. Install the motherboard baffle on the chassis, and then install the motherboard, which greatly reduces the dislocation of the motherboard, but the mounting screw hole is still not completely aligned with the copper column nut at the bottom of the chassis. At this time, the copper column nut can be replaced with a plastic mounting column, because the plastic has certain toughness, and it can be inserted into the mounting hole of the motherboard with a little force.
4. The extra metal blocks on the side of the motherboard baffle can also be blocked by the PCI baffle, which can also correct the dislocation of the motherboard. Of course, the premise is that this PCI gear cannot be equipped with a graphics card. Finally, the transformation is completed, and the motherboard and baffle can be installed in place.
