You bet. I shop for cases first visually, because you have to like what your PC looks like. Then functionally, does it have all the options I need/want and will it fit everything. You also have to search in the range you are willing to spend. If you are going for a budget build, there are plenty of $50 cases out there that will work just fine. Your money is best spend on other components since your case doesn't make your PC run faster. One exhaust fan is just fine for any average system. Most cases also have alot of venting at the top which helps as well. People overdue airflow all the time.
