Hey,
Which size should be the top fans in define r4? 120mm or 140mm? I've been reading that R4 supports 140mm fans but also 120mm fans too, but im not 100% sure. Also would x2 CORSAIR AF140-LED or AF120-LED fans work as top fans? I want to have some led lightning (blue) coming out of the case. Also would these same Corsair fans work as front/bottom and rear fans?

Fast anwser would be great, i'm thinking to get more case fans soon!
