I going to buy this case.
Front: 2 X 120mm RED LED Fan with Filters (included)
Rear: 1 X 120mm (included)
Top: here go the Corsair hydro series H100i's dual radiator

And my problem is with the side fan.
I don't know what is better, 2X 120mm Fan or 1*220mm Fan ?
I want red ones, but I can't find any 220mm in red led color.

Off: Is that hard to buy a 200mm fan and use 4 little metal chunks + 4 bolts and make it to fit into 220mm's place ? Or u know any other solutions?
