Rear Mobo Dimensions

[thexshadow]

Hello all, I have no idea where to post this, so it's going here (since it is going to be a SFF case when its done).

Anyways, I am modeling a case I am going to be making in Autodesk Inv. I have almost everything built, I'm just missing some dimensions. I have the image below which I am going off of, but it missing the dimensions between the mobo and the bottom of the I/O plate cut out. It makes it difficult to know how tall of standoffs I need. Does anyone know this dimension?

.088" +/- .010" top of standoffs to bottom of I/O aperture

Perfect, thanks for the pdf, I found what I'm looking for now.

So here are my dimensions. I just want to make sure I have everything correct here before I proceed building the case.

And sorry for the measurement clutter.

sorry man, no time tonight to run through the units conversion...I'll try tomorrow

good call having someone check you work before actualizing it on the material plane though

Awesome, thanks.

Those measurements are based off of this too if you were wondering. I didn't find everything I was needing on the above pdf, but then I stumbled across this one.

That's a really good PDF, here's the one for PCIe card physical specs:

Took me some time to find that back then...

And yeah, it's 99% correct. I tested it

One hint though - the GPU I got here (EVGA GTX 650) had some mini Displayports outside the cutout that's in the spec up there.
Either it's not the most recent one, or the manufacturers don't adhere to it strictly.
I had to widen it by 5mm - see design thread of the mITX case of mine for some note on this..
