Michelle, You will, no doubt, get some practical advice here from
experienced builders. To supplement that, here's a page showing ATX
specifications. It shows dimensions on page 10. You could compare your
board to these standards; first to see if it is an ATX board, and second to
see if it is standard.

You may get some help identifying the board here:

>Hi, I wonder if anyone can help me as I'm having a slight problem.
>I have a motherboard which I would like to put into a tower.
>The problem is finding the right tower.
>The board stands 12" high when placed the right way up, and 9 1/2 " across.
>I'm told I may need an atx casing, but is there a general size for towers?
>I seem to be having trouble getting one to take this mother board.
>There is no way it will go into a midi size tower, which is a pain, as I
>have a few of them spare.
>Hope someone can throw some light on this for me.
