The ATX Adapter boards I designed up in EasyEda and ordered through JCL showed up in the mail and seems I got the ATX 24 Pin vertical pin dimensioned correctly on the board. I do have the Gerber file in the files for this project for just the ATX connector. I did get everything soldered up except the male terminal connectors since I am still waiting for those to show up. Just hoping I got those mounting dimensions correct.
There are pics of the everything soldered to the board (except the male terminals as mentioned) in the files.
