Yeah sorry for mixing units like that. I think of it as a 19" rack and know that refers to the width, but I had to look up the height of a 4U chassis and Google told it to me in cm, so then I went with that for that dimension.

Totally fine, my brain just isn't used to processing imperial measurements in the same sentence as metric, so I thought the conversion might help others in the same place!
