    This isn't really a Mod Guide but there's no better place to put it.

    Here is a list of dimensions you may find useful while building your own case. Some of them I measured myself so they are accurate to about plus or minus 1mm. All dimentions are in mm. Width is the width when looking at the object head on and Depth is the width of the object when looking at it side on.

    Motherboards - Various Form Factors
    [​IMG]

    ATX PSU
    H: 86
    W: 150
    D: 140

    3.5" IDE Hard Drive (I can't understand why they're called 3.5" when the width is actually closer to 4")
    H: 25
    W: 102
    D: 146

    Optical Drive
    H: 41.3
    W: 146.0
    D: Can vary between about 170-220mm

    DDR Memory
    H (From MB PCB): 30 (Can be up to 48mm - more with heat spreaders)
    W: 134

    AGP Cards
    W: 311.99 (Yes I know no cards of this length exist but apparently our cases are supposed to support them! For reference my GF4 Ti 4400 is 216mm wide)
    D: 107.96


    Stuff still left to find:
    Maximum Width and Depth of PCI cards.

    I'd appreciate it if anyone else could contribute to this list. It's hardly complete. Also if there are any corrections to be made or any inaccuracies in some of the measurements then please post!

    :)

    This is very good information.
    I would like to see the spots for the screw holes.
    (For people who make their own case)

    how about standard screw threads/sizes? especially on non-custom cases that use wierd screws, like lian li's thumbscrews?


    i really just want a good reason to buy a tap&die set :)

    For atx:
    http://www.formfactors.org/developer/specs/atx/atx2_1.pdf

    Page 12 has the mounting point locations. The dimensions are given in decimal inches of all things.

    For hd holes you can check some HD datasheet... For example you can look at Maxtor support page (here is the linke for a fireball SE drive).

    The same for FD (try Mistumi) and CD-ROM....

    I'm using all that information for the design of my second clear case....

    GeeK!

    Found more data:

    - here is the datasheet for a CD-ROM; on page 2 you can see all the physical data including mounting holes;

    - here you can find the specs for slim line CD-ROM (see page 2)

    - finally, here is the datasheet for standard floppy drive.

    More to come as soon as I find other specs.

    Hope it helps! :naughty:

    GeeK!

    Yep! Mitsumi is a great source for hw physical dimensions....

    Here is a wheel mouse datasheet with all dimensions on page 2.

    GeeK!

    EDIT: for PSU srew holes, see page 24 of this document...

    Another update:

    Here you can find a dwg file with the rear panel for an ATX cabinet (see the lower left drawing).

    Useful if you plan to make your custom back plate.

    GeeK!

    Great thread this helps me a ton with my new cube case ;)

    One thing I am having trouble with is the length of the GFfx, GF4 and upcoming ATI 9900. I see that the GF4 is 216mm long (8.5"), but from where is this measured (back of metal plate)?

    In my case desgin, I am planning to leave 8.764" of room between where the back of the metal plate on the card touches the rear of the case and the front of the case. Is this enough room for the GFfx? Does anybody know how long the new ATI 9900 will be? I'm looking at either of those cards to put it.

    Finally, does anybody know how far over the agp opening is supposed to be from the IO opening?


    Thanks a million for any help!!!

    You guys rock!

    Maximum PCI length.

    I remember reading that the maximum length of a PCI card is 8.6" I think this was in an Intel developer PDF about cooling. Let me see if I can find the link.

    I have never seen a PCI card come even close to 8.6" though. I have a SB Audigy 2, a long pci card, and that is only 7" long.

    Anyone know where to get I/O shield dimensions from?

    I could take my PC apart and use it's shield as a template but thats a major nightmare!!!!

    For Meblin: the I/O shield dimensions are 158.75mm by 44.45mm.

    For Jason L: the AGP opening can be treated like a standard PCI opening. The ATX standard sets a total of 7 openings for AGP/PCI/ISA cards; AGP is the one nearest to the I/O hole.

    I have an AutoCAD drawing of an ATX backplate.. I'll post it this night...

    GeeK!

    Here is the drawing. Note that it's flipped horizontally and it's seen from the inside of the case...

    Hope you'll use it!

    GeeK!

    I was thinking of something more along these lines:

    Re: Re: Dimensions for anyone making their own case

    Well, actually I think it's from the good old floppy disk terms:
    A 5 1/4 " floppy as well as 3 1/2" floppy. Am I right?

    But it could be that the HD-plates are as big as that too...

    NB: By the way, I just measured a couple of my own PC-parts, and it's the same messurements - :hip: cool ! :hehe:
