Specifications side by side

How to choose the right Rosewill case

1. Check motherboard compatibility first

   Your motherboard size dictates the case you need. The Rosewill Mini-Tower supports microATX boards, making it ideal for compact setups. If you require larger form factors, the Hearth NAS PRO accommodates E-ATX motherboards for high-end servers. The ATX Mid Tower fits standard ATX boards for gaming. Always verify your board size before purchasing to ensure a proper fit and avoid installation issues later.

2. Match tower size to your space

   Tower size determines how the case fits on your desk. The Mini-Tower measures 7.8 by 15.2 inches, offering a small footprint for tight spaces. The ATX Mid Tower is slightly wider at 7.67 inches but taller. The Hearth NAS PRO is significantly larger, measuring 15.8 inches wide. Consider your desk dimensions and available floor space. A smaller tower saves room, while a mid-tower or server chassis provides more internal volume for components.

3. Evaluate included power supply needs

   Some cases include a power supply unit, which simplifies your build. The Rosewill Mini-Tower comes with a 400W power supply included. This is convenient for budget builds or users who do not want to purchase a separate PSU. Other models in this list do not mention an included power supply. If you already own a compatible power supply, you can choose any case. Otherwise, verify if the included unit meets your system's power requirements.

4. Assess radiator support for cooling

   Radiator support determines your liquid cooling options. The Mini-Tower supports up to a 280mm radiator. The Hearth NAS PRO supports a 240mm radiator. The ATX Mid Tower is compatible with radiators but specific sizes are not listed in the attributes. Check your cooler dimensions against these limits. Larger radiators generally provide better cooling performance. Ensure your chosen radiator fits within the specified maximum size for optimal airflow and component clearance.

5. Consider side panel visibility

   Side panel material affects aesthetics and visibility. The ATX Mid Tower features a tempered glass side panel, allowing you to view internal components and lighting. This is preferred by gamers who want to showcase their build. The other models do not specify glass panels, implying solid metal sides. Glass panels add weight and may require careful handling. Choose a glass panel if visual appeal is a priority for your setup.
