When I think "budget friendly" in chassis design, I think of most of the cases offered currently under $60. What I do tend to find are cases that may look good, but then they lack installed fans, tool-lees features, or both. Of course, the other option is to get an ugly "box" that has more fans, but lacks in appeal and likely will end up under the desk or buried behind other things over time. It is a rare occasion that you can get good looks, loads of cooling, tool-less features, and a few other options to coincide with the term "budget friendly".
