Currently using the 500r, just using the fans that came with the case, 2 120mm front fans and the 200mm large side fan and the single 120mm fan on the back and the evo 212 I bought. I was wondering if the fans that came with the case were good or should I replace them with other ones? Also there looks to be space for 2 120-140mm fans at the top of my case, any recommendations?
