For the 80% case are there any anodizing errors?
The Tex Grey 80% has a 'burn' mark in the bottom half of the case.I believe that is a manufacturer's defect since photos of the case on mechanicalkeyboards.com also have the same 'burn' mark. Other than that, there are no anodizing errors that I see.
The Vortex Blue 80% case has spotty anodizing in the bottom half of the case and there are random holes that are not anodized. Those holes are not visible when the case is assembled.
