ASRock's Z590 Taichi Has a New Trick: A Gear That Actually Spins
ASRock has used a gear pattern as part of the design on its flagship Taichi motherboards for a few generations, but as you can see in the video below, now the gears actually spin on the Z590 iteration of the motherboard.
As Chinese publication XFastest demonstrated in its Z590 Taichi review, the gears on the I/O cover rotate in a clockwise fashion. ASRock even added a special option inside the motherboard's firmware so you can control the spinning interval.
