That's the exact HHKB I have and trust me, it's a noisy rattly mess compared to a good mech.
Like just lightly glide your fingers across the keys and you should feel/hear the rattle. That same rattle continues as you type, it's just mixed in with the sound of bottoming out.
For comparison, my mech is a solid feeling piece of aluminum, the keys have 0 wobble, and there are no rattles at all.
It's night and day, I could never go back to a HHKB.
