"Asus cm557" is a desktop model number , look on your motherboard for the actual motherboard number. (easier to explain)
I know the ostrog case very well I have 2 top, 2 bottom, 1 front, then cooler on rear ports.

the trick is the motherboard and what it will permit to connect, and what "fans models you got"
