Hi. Just interesting it's worth to fill that case with fans. There is extra fan places: 2 top, 1 rear, and 1 bottom. What fan size to use 140 mm or 120 mm? What type to use static pressure vs air flow? Brand, model? What is good for silent operation?
I would put one at the back and top left to exaust the air.
For the fan size i would go with the 120mm and put them from 20 to 50% for lower noise.
The brands I would pick would be Corsair and Thermaltake.
Here are some fans from each:
