Accurate Blank Motherboard & PCIe Card Models - Great starting point for a custom case design


High precision, low detail blank models of ATX, microATX, Mini-ITX, and HPTX form factor motherboards with mounting holes and IO opening + standard single/dual slot and low profile PCIe cards in their proper relationship to the motherboard. All dimensions from official specs.

Model created by subtec. Uploaded with permission.

Editor's note: I can personally vouch for the accuracy of this model. Project Nova was designed around it and the...

Great resource thank you.
Just one question.

Where does the 2.1082mm distance between the edge of the motherboard and the IO Cutout plane come from.
I was looking for this dimension in the ATX specs.

Is this plane supposed to be the inside of the case wall or the outside (if so how thick was the case wall inteded to be?)

It's to the inside of the case wall:



Datum 0,0 is 0.4" from the board edge, so the distance from the board edge to the case wall is 0.083", or 2.1082mm

Hi, Thanks for this model...

If only I knew about this one before.


Is it safe to take this work, remove every unecessary object (like text, E-atx etc etc...) Minimize it and upload it with a mention to this file?

I mean Aibohphobia is not here anymore and I can't find any "Subtec" User to ask permission about...



I would like to upload it on my thread and website, with of course a link to this great ressources.

Hello, in the Protacase Website they say 1.651 mm between inside the enclosure to the board edge. Here 2.1082mm. It's a huge difference no ?

I wouldn't call 0.5mm a huge difference in this application. I don't know where Protocase derives their number from, but the ~2.1mm is from the ATX specification.

There is fews mistakes that i notice in protocase anyway.

It's specified: "We oversize our cutout by .005" (.13mm) all around compared to the form factor recommended opening. (This allows the IO plate snap in a little easier)"

But its not always counted even in the same detail view.
As a example: Figure 6.4 | ATX Front View => the i/o cutout weidth is ok but the i/o cutout hight is not
(if you do some math 51.75mm - 7.3mm = 44.45) there the oversize haven't been counted. Same mistake for the micro atx but 44.58 instead of 44.70.

Hello, i notice that the MB holes are 6.17mm from the Egde (PCI Side). Should it be 6.35mm ?

Yes, although the holes are in the correct location relative to everything else. Rather, the board is the wrong size. Mini-ITX is usually specified as 170x170mm, right? In fact it's not. It is 6.7x6.7", which comes out to 170.18x170.18mm. That's why there's a 0.18mm discrepency.

It's not an error that's likely to affect your design in any way, but it's still good to know.
