As a project for my BTEC Level 3 Mechanical Engineering qualification I will be building a test bench that can house mini-ITX, micro-ATX and ATX motherboards. So far I have struggled finding any images that show the dimensions for the screw locations for all of the motherboards.
My request is that someone in this community can recommend sites to look at or even link me to the images.
Thank you in advance.
tl;dr I need images of motherboard dimensions (ATX, mATX & mITX)
