This will be a publically available dataset of AutoCAD files that can be use for custom case design. I have been collecting data from various sources to create a standard collection of 3D models that can be used for "fit checks", visualizations, and the like. Here are some examples of the info I've found so far...
This is still just a small example of the stuff I already have. I also have the PDF documents that define the ATX specification.
The problems that I'm hitting up involve more difficult dimensions to determine including the following:
-backplane dimensions and distances
-5.25" drive bay internal dimensions and mounting hole locations
-same for 3.5" drive bays
