Software guy going hardware here, throwing down on machining hardware here in China next week. Funnily enough, I actually saw magnesium being machined for the first time on Monday: a part for a medical device. The machinist said it requires different coolant (white in his case) but sources online say you can go dry as well. You also need different fire suppression systems in order to safely machine it, as the chips may burn from friction on blunt tools or excessive feed rates. I wondered why bother, so I just looked it up, assuming in the NeXTcube case it was aesthetics. It does not match aluminium in terms of its thermal conductivity, but allegedly may be one-third lighter, more dent-resistant, more easily machinable, and better able to shield electromagnetic radiation and dampen vibrations. Seems a lot to pay for some nominal benefits unless specialist applications demand it. PS. Never saw a NeXTcube except in a museum maybe, but earned some of my first Unix software money programming embedded cryptographic applications for the abortive Cobalt Qube and Raq ecosystem, incidentally the only MIPS target I've ever written for, but no doubt NeXTcube-inspired.
