I'm not saying it is, it's a response to this, which I should have quoted:
> having a hollow tube-like structure made from metal would be very wasteful because you would have to mill out the entire core (unless it’s cast metal?)
Basically, I'm saying those aren't the only options
Ah ok, yes, not every hollow metal part has to be milled from a block. I was saying that because the original comment mentioned the iMac, which is milled from solid material AFAIK. I probably should have made that more clear.
