Mid-Tower E-ATX Case

The Antec P20C is a mid-tower chassis built for E-ATX, ATX, Micro-ATX and ITX motherboards. It targets builders who need room for long graphics cards and dual radiators in a steel and plastic frame with a tempered glass side panel.

Check Motherboard Standoffs and Front-Panel Headers

Verify that your motherboard tray matches the supported form factors and that the board provides a USB 3.2 Gen 2 Type-C header for the front port. Confirm the CPU cooler clearance limit of 170 mm and the maximum graphics card length of 375 mm before selecting components.

Bundled Fans, Splitter and GPU Bracket

Three pre-installed 120 mm PWM fans at the front come with a 1-to-4 splitter cable for simplified wiring. A GPU support bracket is included for vertical or horizontal mounting, and eight rubber grommets plus three cable ties assist with cable routing.
