Antec Performance 1 FT E-ATX Full Tower Gaming Case – White

The Antec Performance 1 FT is an E-ATX full tower case designed for high-end gaming builds and workstations that demand space for large components and extensive cooling. It features dual tempered glass panels, integrated temperature monitoring, and support for modern GPUs up to 40 series, solving the cable management and thermal visibility challenges of complex PC builds.

• Temperature display monitors CPU and GPU — A dedicated display on the I/O panel shows CPU or GPU temperature at a glance, switchable via a front-panel button. Requires Antec iUnity software installation.
• Fits RTX 40 series and extreme cooling — Supports GPUs up to 400mm, front 420mm radiators, and up to 10 fans simultaneously, accommodating current-generation high-end components without compromise.
• Dual tempered glass showcases components — Both side panels are 4mm tempered glass, giving a full view of internals and RGB lighting from either angle.
• Organized cable management system — Ten velcro straps, two cable covers, and a removable top cooling bracket keep cables hidden and organized throughout the chassis.
• Front Type-C 10Gbps port included — Mainstream USB Type-C on the I/O panel enables fast file transfers without reaching the motherboard.

• ✓ Supports E-ATX, ATX, Micro-ATX and ITX motherboards.
• ✓ Fits graphics cards up to 400mm in length, including RTX 40 series.
• ✓ Accommodates CPU coolers up to 175mm tall.
• ✓ Power supplies up to 245mm fit standard; extends to 440mm if bottom HDD bays are unused.
• Note: Temperature display requires Antec iUnity software to be installed on your system for real-time monitoring.

Best for:

• Builders of high-end gaming or workstation systems
• Liquid cooling enthusiasts needing 420mm front radiator support
• Cable management and aesthetics-focused builders
• Users who want real-time temperature monitoring from the case

Trade-offs:

• Small form factor or compact build plans; this is a full tower at 522 × 230 × 522 mm.
• Builders avoiding software installation; iUnity is required for temperature display functionality.
• Systems with power supplies longer than 245mm or 440mm depending on HDD configuration.
• Passive or minimal-fan cooling setups; the case is optimized for multi-fan and radiator configurations.
