Here is a computer case with an open frame inspired by helicopters. The Thermaltake AH T600 has tempered glass panels on each side and at the front. It has dual GPU placement options, so you get to choose to display your graphics cards vertically or horizontally.
The case has a modular design, so you can take it apart to make changes at your convenience. It is designed to promote better airflow and has Type-C and other convenient I/O ports.
