My new custom pc had a very bad humming sound. So I thought it's from ryzen stock cooler. But then I found out its from the hdd vibration. Apparently if it even touches the case slightly the whole case vibrate giving annoying noise. Now after searching a bit I tried adding some foam padding but the drive bay is so packed that it has space for only hdd(3.5"). So I took the hdd and placed it in front in open area and added some foam underneath it.( the vibration is gone now). Can you please check and say if its OK? The img:
