PC cut out sizes?

[Edward78]

I did a case in Protocase & I think I have the cutouts right... I have a slim ODD, 3.5 & a Flex ATX... The 3.5 & Flex have been found online, not the slim ODD though... Flex ATX PSU & 3.5
Flex 40.50 81.50
3.5 4 in 1 in
Slim ODD 5.75 in ???

Can you not find dimensions of the ODD from manufacturer?

I am sure the width is right, but the height II had to look at the specs od a slim odd...
