my pc desktop is a Acer G3-605 Predator equipped with a microATX motherboard from Acer.I want to change the mobo for an ASUS ATX(consequently the UPS) but I'm not so sure that the new Asus ATX will fit in the predator case.(concerning the fixations/number & place). A technician from Acer said to me that my new card is not referenced by Acer. Ok, but does it mean it's not possible to fix it in my case or simply that Acer don't like the substitution?
