Best budget (50-100$USD) Mid-Tower Case?

I am building a regular ATX (Asus Sabertooth TUF z77) PC with a GTX 670 from EVGA and regular air cooling and I would like some suggestions on Mid Tower cases! I would want something that looks clean and has a gaming feel with great airflow! Thank you! :) 

Take a look at the NZXT Tempest 410.

The tempest looks pretty dumb to me but it is really good for airflow.

Get yourself the COOLER MASTER HAF 912 and buy Nactua fans and a Nactua CPU cooler.

I second the Cooler Master HAF 912.
