The global leader Nvidia launched its latest and greatest graphics card, the RTX 4090, in late 2022. The GeForce RTX 4090 is a beast that can run almost anything on a PC. However, with its powerful performance comes its huge size.

If you already have the 4090 or you're planning to purchase it, you'll most likely need a different case to fit it. Most traditional cases are not big enough to fit the RTX 4090. Overall, a good case ensures better cable management, ventilation, and, most importantly, a good-looking setup.
