SilverStone ALTA D1 is a workstation mega-tower chassis designed for various applications in hyper-converged and high-computational fields, epitomizing modularity. It supports industry-standard motherboards up to SSI-EEB workstation motherboards and custom form factor sizes like Supermicro proprietary boards measuring 15.12" x 13.2". The chassis boasts 11 expansion slots, allowing for a dual-CPU, multi-GPU system, making it ideal for high computational tasks. The highlight of this case lies within the top half of the chassis, which features modular cages that enable users to install components based on their system requirements, offering the freedom to redefine system component locations and explore endless configuration possibilities. The upper half of the chassis incorporates modular bays. Depending on system requirements, these bays can accommodate the included modular drive cages or cooling brackets. The accessories include two modular cages, each supporting 2 x 5.25" ODD, 2 x 3.5" HDD, or 4 x 2.5" SSDs. On the cooling side, two fan/radiator brackets are included, supporting 3 x 120mm radiators or a single 360mm radiator. If the system is intended for mass storage, users can mount the modular bays with their desired devices (additional modular cages can be purchased separately to increase overall storage capacity). For extreme cooling systems, the modular bays can be fitted with the cooling brackets for exceptional cooling efficiency. Users can also mix and match cooling and storage components to achieve the desired balance of efficiency and capacity. For high-end systems designed to accommodate high computational power draws and requirements, the support offered by a secondary PSU can be beneficial, providing extra performance and stability. Therefore, a secondary PSU bracket with 4 expansion slots is included. This bracket adds an additional 4 slots to the standard 7 slots on the chassis, resulting in a total of 11 expansion slots, which allows for the installation of multiple workstation compute cards, such as the A6000. In conclusion, the ALTA D1 is constructed with high-grade steel, providing exceptional durability and robustness for the most demanding applications. Its modular design, extensive cooling options, and support for various components make it an ideal choice for building high-performance workstations. The ALTA D1's flexibility and capacity ensure it can meet the diverse needs of users in hyper-converged and high-computational fields, making it a top-tier choice for professionals seeking a reliable and customizable chassis for their systems.
