I know this is probably a long shot, but I bought a base model 4000D case a month or two ago which comes with a solid front plate and I regret not getting the Airflow model, which has a more open and airflow friendly design (who'd have thought).

Also, if a Corsair rep (or anyone who knows) happens to come across this; is it possible to just buy the Airflow front plate separately? I'd definitely be willing to do that if nobody wants to trade, but I'm not sure how.
Thanks!
