Description
Introducing the FSP U660 ATX Ultra Tower Multi-HDD Black Desktop Chassis. Purpose-built for professionals and power users who require exceptional storage capacity and robust performance. Designed to handle demanding workstation environments, this ultra tower case provides a solid and scalable foundation for systems used in data-intensive tasks such as video editing, large-scale storage management, and scientific computing. Its durable construction and expansive internal layout make it a reliable choice for users who need both performance and long-term dependability.
One of the most defining features of the U660 is its unmatched storage capability. Supporting up to eighteen 3.5-inch hard drives and four 2.5-inch solid-state drives, this chassis is ideal for users who need vast amounts of data storage within a single system. Whether you are building a media server, backup solution, or data processing workstation, the U660 offers the flexibility to configure storage exactly to your needs. This level of capacity sets it apart from typical ATX cases, making it a standout option for storage-heavy builds. In addition to its storage advantages, the U660 delivers impressive expansion capabilities. With nine expansion slots, including support for vertical GPU mounting, the case allows for multiple graphics cards, capture cards, and other add-ons. It supports ATX, Micro-ATX, and Mini-ITX motherboards, giving builders flexibility when selecting components. Graphics card clearance extends up to 420mm when the HDD bracket is removed, ensuring compatibility with high-performance GPUs, while CPU cooler support up to 180mm accommodates powerful air cooling solutions.
Cooling performance is another key strength of this chassis. The U660 is designed with an optimised airflow system that promotes efficient heat dissipation, essential for maintaining stability during heavy workloads. It supports multiple fan configurations across the front, top, bottom, and rear, as well as radiator installations up to 360mm at both the front and top. This allows users to customise their cooling setup according to their performance requirements, ensuring that even high-powered systems remain cool and reliable under pressure. The chassis also incorporates modern connectivity and durable construction to enhance usability and longevity. The front I/O panel includes USB 3.0 ports and a USB Type-C connection, providing fast and convenient access for peripherals and data transfer. Built from high-quality 0.8mm SPCC steel, the U660 is engineered to withstand continuous use while protecting valuable components. With its combination of extreme storage capacity, flexible expansion, and strong cooling support, the FSP U660 stands out as an excellent choice for building a powerful, future-ready workstation.
