Accurate motherboard pdf for case design

Hi Folks,
For my Tubika build I’d like an opaque case so I need to mod the current case file to put LED and display holes etc. If the PDF of the mobo on the DITY resources page accurate for this? Or would I be better off exporting from the eagle file?

Check both options against some actual fysical measurements of the PCB and use the best one.
I’ve always been fine using the Eagle export.
