Setting a budget was a crucial step for me. I found that mini ATX cases come in a wide range of prices. I compared features versus cost to ensure I was getting the best value for my money. I also kept in mind that spending a little more on a quality case could save me money in the long run if I needed to upgrade or replace it.
