When it comes to pc tower cases, enthusiasts often find themselves torn between two exceptional options: the Phanteks Eclipse P300A and the Cooler Master Cosmos C700M. Both of these cases have garnered significant attention in the market due to their impressive features, design, and performance. In this comparison, we'll delve into the details of each case, highlighting their strengths and weaknesses to help you make an informed decision.

Design and Build Quality

The Phanteks Eclipse P300A boasts a sleek and modern design, with a tempered glass side panel that showcases your build's internals. The case features a sturdy steel frame, aluminum exterior, and a sleek mesh front panel for optimal airflow. Weighing in at approximately 6.5 kg, the P300A is relatively lightweight and easy to maneuver.

On the other hand, the Cooler Master Cosmos C700M has a more aggressive and futuristic design, with a curved tempered glass side panel and a robust steel frame. The case features a unique "butterfly" design on the top and front panels, which not only adds to its aesthetic appeal but also enhances airflow. Weighing around 14 kg, the C700M is significantly heavier than the P300A, indicating a more substantial build quality.

Interior Space and Cable Management

Both cases offer ample interior space for your components, but the Cooler Master Cosmos C700M has a slight edge in terms of overall volume. The C700M can accommodate up to E-ATX motherboards, while the Phanteks Eclipse P300A supports up to ATX motherboards. In terms of cable management, both cases feature clever routing options and tie-down points, but the C700M's more extensive interior space makes it easier to manage cables and hide them from view.

Cooling Options

The Phanteks Eclipse P300A is well-ventilated, with a mesh front panel and support for up to 3 x 120mm fans or 2 x 140mm fans in the front. The case also features a single 120mm fan exhaust at the rear and supports up to 2 x 120mm fans on the top. In contrast, the Cooler Master Cosmos C700M offers more extensive cooling options, with support for up to 4 x 120mm fans or 3 x 140mm fans in the front, as well as a single 120mm fan exhaust at the rear and support for up to 2 x 120mm fans on the top. Additionally, the C700M features a unique "heat column" design that helps to dissipate heat from your components more efficiently.

Other Features

Both cases feature removable dust filters, USB 3.0 ports, and HD audio jacks on the front panel. However, the Cooler Master Cosmos C700M has an additional 4 x USB 3.1 Gen 2 ports and a dedicated fan controller, giving it a slight edge in terms of connectivity options.

Conclusion

Ultimately, the choice between the Phanteks Eclipse P300A and the Cooler Master Cosmos C700M depends on your specific needs and preferences. If you're looking for a sleek, modern design and excellent airflow at an affordable price point (around $100), the P300A is an excellent option. However, if you're willing to invest in a more premium pc tower case with advanced features, superior build quality, and extensive cooling options (priced around $250), the Cooler Master Cosmos C700M is the better choice.

In summary, both cases are exceptional examples of pc tower cases, but they cater to different segments of the market. The Phanteks Eclipse P300A excels in terms of value for money, while the Cooler Master Cosmos C700M offers a more premium experience with advanced features and superior build quality.
