Motherboard alignment during installation?

[bgc99]

The screws that hold the motherboard in the case are tiny compared to the holes in the motherboards, there's alot of play there. What's the best way to align it so the expansion cards seat properly?

Thanks,
BGC

Leave a couple mm between the case and the left side of the motherboard

Leave the screws loose when mounting the board - then place all cards in their slot and tighten all the screws.
This way the mobo is perfectly aligned in the case/slots
