Is this the PSU or 3.5 HDD that is making this sound?

Hardware Hub Storage

Which is making this sound and should I be worried? Note some of clicking is the mouse.

If above sound sharing link doesn’t work try this: psusound | Whyp

Is the sound normal of a HDD? My case is mesh on all sides.

Thanks. The sound makes a mesh case a downside.
