The full interior of the case is the firey red we’ve seen hints of in the exterior, with some black styling in the PCI brackets and optical drive slots. The inside of the side and roof panels are also black coated.
Each PCI bracket is clip controlled, but they do feature holes to give you the option for screws to be used.
The motherboard plate has a giant hole in it to make cable routing and CPU back plate switching far easier. This isn’t the only one either.
There’s ones at the bottom, on the side; there’s little inserts into the rear of the motherboard tray all over the place.
