Slide the central spine to fine-tune clearance between a massive multi-slot GPU up to 350mm long or a taller CPU air cooler — with a pre-installed PCIe 4.0 x16 riser cable included right in the box.

Why SFF Builders Choose the Antec Performance 1 M
- Boutique CNC Aluminium Craftsmanship: Thick, bead-blasted anodised aluminium panels with precision-milled ventilation slots deliver rock-solid structural rigidity and a minimalist workstation aesthetic.
- Customisable Central Spine: Shift the internal divider to tailor your build — give extra room to a 3.5-slot flagship GPU (up to 78mm thick) or slide it over to fit a beefier 85mm low-profile CPU cooler.
- PCIe 4.0 x16 Riser Included: No need to spend extra on a third-party riser; Antec includes a shielded PCIe 4.0 x16 riser pre-routed for plug-and-play installation.
- Tool-Free Push-Pin Panel Access: Side, top, and bottom panels detach effortlessly via secure ball-catch push pins, allowing full 360° interior access during assembly and cable routing.
- Direct Dual-Chamber Airflow: Both CPU and GPU draw fresh air through micro-perforated side panels, assisted by dual 120mm/140mm fan mounts along the base to exhaust heat rapidly.
