I am looking to buy a budget decent pc case and I found the DeepCool Tesseract, which I think is good enough for the money. The thing is, there is only one front fan and 2 top fans. Right now, I will just leave the front fan and the back fan (Intake and Exhaust), but in the future I am thinking how to maximize the airflow - Should I place the 2 top fans to be 1 Intake and 1 Exhaust or leave them both Intake (Having 3 Intake and 1 Exhaust). If you have any other ideas, please feel free to help.
