Problem on fixing mobo on the case board, HELP ME!

[cybeijing]

When I was fixing my motherboard on the case board, I found the none of the holes on these two boards match as they suppose to. The manual of mobo said I can still fix it by cutting the lower portion of the spacers (those little plastic stuff) and pluggin it into mobo.

Now I am wondering without the fixation to the case board, how can the mobo be fixed?

BTW, they are a baby ATX board and a ATX case.

Thanks for you guys help!!

some ATX cases have numerous mounting holes to accomodate AT, ATX, microATX etc. Others will only fit one or another of them.
