Antec Performance 1 M Aventurine Mini-Tower Case, Black

The Antec Performance 1 M is a Mini Tower enclosure engineered for ITX motherboard-based systems. Its construction combines steel, aluminum, and plastic, resulting in a solid frame with a focus on functional design. The case measures 175 mm wide by 424 mm deep, offering a compact footprint suitable for space-conscious setups. The exterior maintains a minimalist aesthetic with solid side panels and a black finish, catering to users who prefer an understated appearance for their build.

Internally, the layout is optimized for specific component sizes, supporting SFX or SFX-L power supplies up to 130 mm in length and CPU coolers up to 125 mm tall. Thermal management is handled via bottom-mounted cooling, with support for two 120/140 mm fans or a corresponding radiator. The case features a configurable rear panel that offers either a 3-slot GPU configuration or a 2-slot layout to accommodate taller air coolers. A PCIe 4.0 riser cable is included to facilitate vertical GPU mounting, and the design incorporates cable management provisions and dust filters.
