Compatibility notes
This Mini-ITX case prioritizes a panoramic vertical presentation rather than minimum volume. A 330 mm graphics card is the listed length ceiling, but card width, power-cable exit and the precise orientation of the connector must also be checked. Official cooling support is a single 120 mm radiator; user modifications for larger radiators are outside the specified fit. Drive cages can affect airflow and cable space.
- Do not treat an unofficial 240 mm modification as manufacturer-supported radiator compatibility.
- Allow clearance above the top exhaust and route PSU leads without blocking airflow.
- Check drive-cage positions before choosing 3.5-inch disks and fan locations.
