When you are just getting started with building your own PCs, you tend to pay more attention to your PSU, GPU, and CPU. In reality, picking the right PC case is one of the most important decisions you get to make. Open frame cases are great for cooling and making upgrades. Take the ROG GR20 Edition 20 for instance: it is an open-frame modular PC case made from aluminum. It has angled, vertical, and horizontal modes.
The GR20 features a reinforced graphics card bracket. It has a crossflow fan for more efficient cooling. This PC case supports graphics cards up to 368mm long and coolers up to 360mm. The GR20 Edition 20 supports 12 x 10.9-inch EATX motherboards. It has a modular IO panel with 2 x 20Gbps USB-C ports. There is a 36mm wide room behind the motherboard for organizing your cables.
