I'll be shopping for a new chassis that has good airflow, preferably something that doesn't have tempered glass side panel. The budget for this is 7K. Some people have suggested to get NZXT S340 but I am not sure how good is the airflow in that case, it is also out of my budget. Kindly suggest me a good case in this budget. Also, how many fans (except for the rear exhaust fan) installation would you suggest to keep the inside temperature of the chassis relatively cool?
