Exact dimensions of 2.5", 3.5" and 5.25" bays?

I'm modeling an atx case just for fun. I need to know the dimensions of the 2.5", 3.5" and 5.25" drive bays. Not the actual drive. Links to actual blueprints of the trays would be nice. I'll need dimensions for other bits to, so if you know anything let me know.

This appears to have the dimensions you want-

I'll read it but that looks like it tells me about the drive and not much about the actual part that holds the drive. Where the mounting points are stuff like that.

Sorry, I read it to be describing the dimensions of the bays, not the drives. They also offer .pdf files showing specs and diagrams of the drives themselves, which would be rather redundant.
