My recent experiences working with vintage machines has made me curious if there's some sort of service for modern reproduction Mac cases. The inner hardware may be made to last, and the system software and UI/UX definitely has staying power, but the plastic is more questionable, getting brittle and either hard to work with, and/or easily broken. I understand in some cases the plastic is an essential part of the aesthetic (it's hard to imagine a Bondi Blue iMac or Yosemite B&W tower in anything but its original form), but I suspect a Power Macintosh 7x00 'Outrigger' desktop case would be almost as beautiful in platinum-colored aluminum as in its original plastic, especially when the plastic is falling apart and as much aged-beige as platinum.
