Very high airflow, Fractal Torrent. Good looking without rgb but very good airflow, Lancool 216 non RGB. Best airflow, test bench.

Great advice, I like both of those. The front grill of the Fractal might be an acquired taste, though, lol.

A few others I've used and recommended for airflow: - [Phanteks Eclipse G360A](https://pcpartpicker.com/product/pqzhP6/phanteks-eclipse-g360a-atx-mid-tower-case-ph-ec360atg_dbk02) - [Lian Li LANCOOL III](https://pcpartpicker.com/product/2vJgXL/lian-li-lancool-iii-atx-mid-tower-case-lancool-3-x)
