I am working on a mysterious case. It has 'out-of standard spec' rear PCI slot openings (and IO opening as well) . See diagram please.


H2 is measured to be 129mm.
H3 (height of pre-installed standoffs) is 10mm.

With these measurements, the PCI expansion slot openings (and IO opening) are cut out at a location too high. My eyeball estimate is about 10mm too high.

So, the motherboard needs to be elevated slightly higher so that the display card mounting bracket can rest onto the case rear panel and be screwed in, and the mainboard's rear IO can fit into the IO opening.

This means, I need to get taller standoffs.

Does anyone know the standard height for H1 ? From my eyeballing above, H1 should be around 107mm ?!

H1 is the distance from the top of the motherboard to the top surface of the case's rear panel PCI slot mounting point.

Please help. TIA.

It's about 108mm.
Thanks.
I figured there are a number of vendors here and so this piece of info should be readily available in their database.
Now I need to find some proper length standoffs now.
