CNC’ed aluminum cases are better for shielding due to their thickness. Aluminum doesn’t do squat for low frequencies - you need steel or something magnetic. But, that adds electrical distortion. The Navy did a study on that decades ago - most of their vehicles are really large steel vessels and they find their way through various sonic tricks. Aluminum doesn't add nearly as much distortion, but if it’s thick enough the Eddy current losses do make for good shielding. Not to mention the better mechanical resonance issue.
There’s also the air flow aspect and how that effects thermal properties of components. A real advantage of CNC boxes is that you can have a heat sink connection anywhere you want. This isn't just an audio thing, either.
