Accurate Blank Motherboard & PCIe Card Models

.SKP & .STEP Accurate Blank Motherboard & PCIe Card Models 2015-12-14

No permission to download

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 motherboard, IO shield, and cards all fit perfectly.

SketchUp model and my conversion of it to .STEP included.

Amazing. Helped me in designing my case.
Well organized, acurate, and overalll good all around.
Josh | NFC's endorsement is good as gold.
This is awesome. Imported to Fusion and everything was nicely organized so I could delete everything except the ITX board which I wanted. Thank you!
This is the best reference I have seen. Thanks!
Exactly what I needed to start case design. Not new to CAD, but this definitely helps.
This helped me make fewer prototypes.
Its a very good tool for case design basics
I have been using this for validation as well
Been going nuts trying to find proper dimensions of PCIe slot, even from official spec sheets. The few bits of data I managed to piece together match up with your models, so I think it's safe to assume I can trust the accuracy to fill in the rest of my missing data.
It's a real nice resource. Perhaps the only bit to fault it on is that it'd be nice if it included just some lines to show the maximum height motherboard components can reach in each area (as that can be quite useful).
I'd love to see some of these resources for other components too, like common sizes for PSU's (even though they don't follow a standard), and it'd be quite nice to see it for 2.5", 3.5" and 5.25" drives...
This is what you need to begin your computer case design.
