Be Quiet! unveils huge new PC case designed for ‘maximum performance’ with room for up to seven HDDs
German hardware manufacturer Be Quiet! has unveiled its latest PC case lineup at Computex 2026, introducing the Pure Base 803 and Pure Base 803 LX—large-format cases engineered for maximum performance and storage capacity. The cases are designed to accommodate builders with expansive cooling and storage needs, supporting up to seven HDDs for substantial data storage alongside high-performance cooling solutions.
The Pure Base 803 models feature robust cooling capabilities with support for up to three 420mm radiators, accommodating custom liquid cooling setups for high-end processors and graphics cards. Additionally, the cases support two 140mm rear fans, enabling effective thermal management for enthusiast-class builds. These specifications position the Pure Base 803 line as a solution for builders constructing workstation or performance-focused systems requiring extensive hardware flexibility.
Be Quiet! also demonstrated complementary peripherals at the Computex booth, including a TKL (ten-keyless) gaming keyboard variant and a branded mouse pad, suggesting the company’s continued expansion beyond its core case and power supply product lines.
The announcement reflects ongoing competition in the premium PC case market, where manufacturers continue pursuing larger form factors and enhanced cooling support to appeal to enthusiast builders and professionals. With support for up to seven drives and multiple radiators, the Pure Base 803 series targets users building high-capacity storage systems or multi-GPU workstations requiring superior thermal performance.
