Glad to hear that you like the case
I'd have to agree with the stock fans, I'm seeing other users that are claiming the same behavior, where the stock fans exhibits some sort of humming noise.
I agree that the Obsidian cases look good... Simple and elegant.
I also think Corsair ship the wrong fans (At least in the 250D) as the filters are quite restrictive making the AF fans struggle. I replaced them with SP optimised (Parvum F1.0's) and that works much better. I have no reason to believe Corsair's own SP fans should work much different, so I believe they should have been shipped with the case instead.
