Most cases that I would call top quality are around $100-$130. I will name some brands I would recommend: Fractal Design, NZXT, Phanteks, Corsair, Cooler Master, Silverstone. However there are many other choices as well those being a few noticeable brands.
I currently use the Fractal Design Define R5 and it is a very good case for airflow and quiet operation. I have also built in the NZXT H440, the Corsair Air, and many Cooler Master Cases and I can say they are all pretty solid, though that is to be expected at their price points.
My personal favorites are the Define R5 because it is just easy to build in and has great quality for the cost. The H440 is a very quiet case but it is a little bit harder to build in from personal...
