I have a xg viper case (not very happy with it maybe replacing) and there are holes for 80 90 and 120 fans in front and back. The only problem is you cannot get a 120 fan in front. So since the airflow is pretty crappy in the case i decided i want to get a vantec tornado for the front to feed my 120 in back. I want to get a 92 vantec since its the same price with much better airflow but i think my case only is ment for a 90. could i successfully mount the 92 using a drill bit to make theads or any other way?
