You might also have a bad drive or a WD black caviar like me.. Very noisy but I can live with that, just load everything else off a ssd and gaming on mechanical.
I can barely hear my machine on idle. Playing a game, I don't care.. Jack the volume! jack the fans
Try put some tape on the edges of the fan filter..

You can remove the dust filters quite easily and replace them, that's what cases the harmonic whine at certain fan rpms for me. I left mine in because I can just turn a nob on the fan controller past it and they are the best dust filters Ive ever used. Never any dust inside my case.
As for you hard drive, I honestly dont know whether its the actual drive to blame. WD Blacks and Seagate Barracudas are known to have their own quirky noises that can be heard easily. For a lot of silence freaks the HDD and PSU as mentioned above become the loudest thing in the case. Vibrating your whole case sounds pretty serious though! You have a Velociraptor or something?
Bad luck on the fan filter, I know it doesnt help to say mine works fine.

Something is making a bad noise or even resonating in your case if it's loud. If you have some loose parts that can move, then fix them, like filters, anything movable or removable that is not hard screwed down. Cages even the riveted ones do make noise quite a but, dampen them.
It's mainly the bottom front panel fan, but the top front panel fan does it slightly too.
Certain RPM's and changes in RPM's make the sound, and removing the front dust filter actually makes it louder, as it lets more sound leak out of the case and doesn't seem to be causing the issue.
There is very faint vibration in the case, but applying pressure anywhere doesn't seem to help anything.
Everything is mounted with anti-vibration mounts, I don't know how to fix this, wish I could just have my PC located in another room.
All 3 case fans have a wobble I can barely see, front two more than the rear one, and the CPU fan which is also a 140mm Noctua fan has practically no wobble.
I think I'm going to have to live with this and try not to hate my PC everyday.
Nothing I do seems to make the sound better or worse.
Maybe it's just airflow in the case making a weird sound or something and that's why nothing I do does anything, I don't know....
