It's on the smaller side, can only fit m-atx but it has a mesh side panel.
It's front panel doesn't have a mesh. It has a version with a wood front panel having mesh for 1k more, although couldn't find it in stock anywhere.

GN/HU (don't exactly remember who) also said it's good even the non-wood version. Not the best, but the airflow is fine.
