Dimensioning mATX base layout

[crissvy]

Hey peeps, i've been working on a little project for a few days now, i'm trying to create an absolute minimal design tray for mATX MOBO, sort of like a template for PC case design where the important part is already done like hole placement, standoffs and cutouts, all properly dimensioned ofcourse. I got the holes in place but i can't seem to find any definitive way of pinpointing the proximity of the backpanel from the holes and the location of the cutouts like I/O and PCi's. In theory it should be possible to pinpoint these things using only the MOBO holes and the height of the standoff, which is 10mm in my case. If anyone happens to know these dimensionings let me know.

Here are some crude renderings done with Pentium 4

Google for the m-ATX specification.
The holes are in a fixed location relative to everything else.

But don't bother with a template. Just get an old dumped mb and use that
