Apple Mac Pro 2019 | New Apple Computer Guide

The metal holes in the new Mac Pro look very cool, but even better, they are designed that way to accommodate the thermal load.

Making those holes deep gets back to the first principle: more surface area means better dissipation. “[The pattern] gives us a lot of surface area, which is hugely beneficial,” Ternus says. The Pro Display has fans for specific components, but the bored metal holes are what keeps that huge panel of LEDs cool enough to run so bright.

I love when great design and engineering need is solved in one solution.
