Phanteks XT Pro Ultra

The Phanteks XT Pro Ultra is a beginner-tier mesh airflow case that ships with four 140mm D-RGB fans — a lot of included cooling and lighting for an entry build, which makes it a standout value in its class. It takes ATX down to ITX boards, GPUs to 415mm, and coolers to 184mm. The catch: radiator support is 120mm-based only (up to 360mm), so 280mm and 420mm AIOs won't mount.

Compatibility

Built around ATX. Make sure the rest of your build uses the same platform before you buy — mismatched sockets, mounts or standards are the most common return reason. Check it in the builder →
