Thanks, Tarou, for the link

It needs some updates (test on a R9700 Pro, and ZM80A-HP), and it is in French but I think babelfish and google give workable translations.
The mod can be done with the ZM80A-HP, but you can't use all the screws to fix the front plate. Anyway 2 screws are enough as it is pressed by the case (very important, the aluminium case participates to the cooling).
