could you move the hdds to the other side?
i dont think id bother ducting the rad fans; it looks like it should exhaust the warm air fine. plus the hdds are in a windy spot so i dont think the warm draft will affect them too much.
or you could try this: duct the rad fan 90 degrees and out the side panel of the case. that'll work (but that side of the case wouldnt have any real cool air intake). maybe a side blowhole is in order
yes, thatll fix you right up hehe (unless you dont want any casefans. since youve already got plenty, im guessing 1 more wont hurt
)
