Hello everyone! Hopefully this message will reach Clint:
The case that was customized by Xidex is either the Phanteks' Evolv Shift X Shift or the Phanteks' Evolv Shift X.
Here's a look of the case: https://redd.it/ae6vwi
Neither case is available anymore, but with some luck someone can reach out to Phanteks Support and see if they have a spare tempered glass...
Cheers from a long time fan!
