The PCB is a work of art as well.
It's a 60% percent pcb with some flex cuts?
Seems a bit much to call it a work of art, unless there is some feature that i'm not familiar with.
Personally, it's one of the first I've seen with both horizontal and vertical flex cuts (most seem to only include horizontal). And when combined with the cuts in the plate, should (and has been said to) offer a consistent typing feel that's pretty awesome to use. Add to this the sound people have got out of it, and it's actually quite a rarity.
So while yes, this case is cool in that you can drop any 60pcb in it and go to town, the original has been optimized for the plate combinations and unique mount solution.
There are plenty of examples of boards with flex cuts in either the PCB/plate or both which do a pretty poor job of creating consistent feel. There's also many that do a good job with feel, but create very inconsistent sound quality, especially in different regions of the board. Boards that mange to do both with PCB/plate design are few and far between.
