Dimension comparison
Price Comparison
The RackChoice 2U Micro ATX Compact Rackmount is priced at C$140.79, while the Thermaltake TR100 SFF Chassis comes at a higher price of C$207.54. This significant price difference of C$66.75 may influence your decision, especially if budget is a primary consideration. The RackChoice chassis offers a more economical option for users looking for a basic and functional case, whereas the Thermaltake TR100, despite its higher cost, provides additional features that cater to more advanced build requirements.
Design and Size
In terms of design, the RackChoice chassis is built for compactness, being a 2U rackmount chassis suitable for Micro ATX configurations. It supports ATX PS2 power supplies and is specifically designed for low-profile add-on cards. On the other hand, the Thermaltake TR100 is engineered for small form factor (SFF) builds with a volume of 18.9 liters. This design allows it to accommodate more powerful components while maintaining a small footprint, making it ideal for both home setups and travel.
Cooling Capabilities
Cooling solutions differ significantly between the two products. The RackChoice features two 80mm cooling fans for intake, alongside a 120mm fan support on the top for the power supply. This configuration aims to ensure adequate airflow for the components housed within. In contrast, the Thermaltake TR100 supports a more robust cooling setup with the capability for a 280mm radiator and 68mm of CPU cooler clearance. The TR100’s design also features a removable PCIe bracket, which may enhance airflow and facilitate easier installation of cooling components.
Component Compatibility
When it comes to component compatibility, the RackChoice supports four low-profile add-on cards, catering to basic needs for expansion. It is designed to work with Micro ATX components, which limits its versatility compared to the Thermaltake TR100. The TR100, however, is optimised for mITX builds and boasts a 360mm GPU clearance, making it suitable for larger graphics cards. Additionally, it provides support for both SFX and SFX-L power supplies, which gives users more flexibility in choosing their components.
Port Accessibility
Port accessibility is a highlight for both products, albeit in different ways. The RackChoice chassis includes front access USB 3.0 ports, which are compatible with USB 2.0, making it convenient for users who frequently connect devices. However, the Thermaltake TR100’s design is more focused on functionality within its compact form factor. While the specific port types are not mentioned, its emphasis on a clean, travel-friendly design suggests a user-friendly layout that prioritizes ease of access.
Build Quality and Portability
The RackChoice chassis is built with the intention of being a functional rackmount case, focusing on stability and basic usability. It does not specifically highlight portability features. In contrast, the Thermaltake TR100 is explicitly designed to be portable, making it an excellent choice for users who want a compact and lightweight solution for travel. The design includes features such as magnetic side panels for quick teardown and assembly, enhancing its portability and user convenience.
Aesthetic Considerations
Aesthetics can play a role in your decision-making process. The RackChoice chassis maintains a straightforward, utilitarian appearance typical of rackmount cases. Its focus is on function rather than style. Conversely, the Thermaltake TR100 aims to make a statement with its sleek design, which is modern and appealing to gamers and tech enthusiasts alike. This may be particularly important for users who value aesthetics in their build, as the TR100 combines functionality with a contemporary look.
Which should you buy?
Choosing between the RackChoice 2U Micro ATX Compact Rackmount and the Thermaltake TR100 SFF Chassis ultimately depends on your specific needs and budget. If you are looking for an economical option that meets basic requirements for a Micro ATX setup, the RackChoice at C$140.79 is a solid choice. However, if you require a more versatile chassis that supports advanced features, larger components, and offers portability, the Thermaltake TR100 is worth the investment at C$207.54. Consider what aspects are most important for your build—be it price, design, cooling capabilities, or component compatibility—before making your final decision.
