Corsair 600t harddrive placement
 

I have the special edition white version, and I've been looking for a way to mount my 3.5's into my 5.25 optical bays because i prefer having nothing blocking the fan on the front. Any good suggestions? Prefer something that will go with the all black interior.

Like these?

Aha! Exactly. Although those are pretty pricey, but they seem to be noise cancelling which is awesome :D.

Your worried about the front fan being blocked in this case ... I wouldn't the case isn't lacking air flow by any means.

I'd say it's ok'ish, not more. While great, this case is designed for water and the fans are rather quiet than powerful.

Pretty sure your local hardware store have a box of OEM 5.25 to 3.5 for like 2$ each. If not, thye might have some retail one that are pretty cheap.
If not, the egg is always your friend.
