If you want mid size, I'm a big fan of NZXT's H440, lots of style but still within that standard computer look. It's built quite well too.
e/ hardcore OC'ers who don't want to deal with minor case modding might want avoid this though; I hear it slightly restricts airflow in order to provide a sound dampening structure
