I'm building a new system, looking for recommendations for good mid/full cases under or around the £200 mark. Also, any recommendations on additional fans are appreciated. : )
200 quids is a lot of money, you don't need that much unless you need it for water cooling.
There are many good mid tower like Fractal Design Meshify C, Cooler Master MasterBox NR600 or Corsair 275R Airflow. They all have perforated front panel.
