I'd go for that, too.
This is an interesting idea, but I don't know how practical it is. On the one hand, I could see dad and me having some fun with a milling machine and maybe even some anodizing techniques (although anodizing aluminum is not something I ever recall dad doing and none of the metalworkers I know do much at all with aluminum). That'd definitely be cool. On the other hand, the industrial design of the processor would need to be handled such that everything on the face (display, controls, headphone jack) was supported from a structure behind the faceplate in order for this to be "easy". Normally, the faceplate has those things all attached to it and then it is attached to the chassis in a few points, which makes removing the faceplate a pretty major undertaking - not something that you'd want to have consumers doing at will, or even something that you'd really want to have technicians doing on a regular basis to fill custom orders unless you included a pretty hefty upcharge for it. Figure a couple hours of technician labor to swap faceplates, another several hours of somebody's labor to design and make customizations on a new faceplate, the cost for the materials involved (a bare milled aluminum faceplate isn't free), and some extra time to handle the special order - it would easily run hundreds of dollars.
