I have put 3x NF-S12A 120mm fans in the front (have 280mm rad in the top) but I'm not sure it has made any difference really. Seems about the same as with the stock 140mm fans. I think maybe I picked the wrong fans and should have put in some with better static pressure ..
The front panel is slightly set forward with motherboard mounts under the brackets as well.
