hi, no h9 elite has more space for internal hard drives, has more glass parts and a more aesthetic design, while h9 flow is designed for greater air flow

The basic design of the H9 Flow and Elite is identical. However, the Elite has a glass lid and RGB lighting. Like the Elite, the Flow has a glass side and a glass front, but has a mesh panel on the top. This massively improves the airflow with fans/radiators mounted in the lid-Google :)
