..before you ask; I've allready tried googling it. ..no luck.
 
This is for a Google Sketchup model I am doing; which I need exact standoff layouts for. Currently, I have the ATX Form factor specifications ; which include the mATX specifications. I need those for E-ATX and XL-ATX; as the tray will support both of those form factor's. This is a practical design, and may be used in the future; so I need these to be exact, manufacturer specifications. I am working within 1/1000 millimeter for this. I have no problem with inch to millimeter conversion; as I know most form factor specification's are imperial.
 
I need full spec's, of course; same as manufacturer's would use. This is not just for the motherboard; it is for the whole case. Till I find them, I will be inputting Form factor for PSU's; and finishing off the back-panel for the I/O port and PCI brackets. 
  
edit: seems the EATX standoff positions, are the same as ATX; just that the board is a little larger. I compared them with the picture of the Classified 200; and see they are near the same, or equal.

    Have you tried looking at the specs for the x58 classified mb's?

    I have the dimensions for the boards themselves; they are allready calculated for, and in the sketchup. The manuals, and product descriptions; don't include standoff positions, unfortunately. I need these, for when I send the design to prefab; so they can cut the pieces, to exact spec.
     
    If I don't have them, I suppose I can just finish the fabrication myself; by drilling out the holes, from a pattern set by the motherboard. I will likely be tapping the holes, for the mounts; just to cut down prefab costs. I would, however; prefer they be pre-drilled.

    Still wouldn't mind having the XLATX standoff spacings. They appear to be about 39.370mm from the bottom row of ATX standoff's; though, I can't be sure about this.

    Guess I'll work wih what I have for now; and maybe export a copy of the tray, for later.

    Have you tried looking at the specs for the x58 classified mb's?


    The EVGA Classified board (except for the E762) are not true E-ATX boards and have the same stand-offs as a Standard-ATX board.  The only difference between a Classified board and a Standard ATX board is that the Classified is about 1-1.5inches wider (front to back), a true E-ATX board is around 3.4 Inches wider (front to back) than a Standard ATX board and has slightly different stand-offs.

    thanks for the clarification; I kinda thought that may be the case. Allready went ahead with the motherboard tray layout; looks alright so far, I guess. Missing the XL-ATX standoff holes; but, thats not really a big issue.

    Now I just have to figure out the PCIe bracket placement; and go from there. The ATX Specification 2.2, covers PCI and older; so not much help there, unfortunately. Doesn't really give proper measurements anyway.

    Guess I'll have to pull out a card and check; though, a plastic ruler isn't ideal for engineering design measurements

    Go to the store and look inside a cm haf 932 case.  It has a cardboard insert taped to the mb backplane with the holes for the extended sizes marked on it.

    heh.. thanks for the tip; but the closest store with a HAF 932 is about 130km away ..nice thought though
