What is one of the best mini itx cases for a budget build? I've been looking at the cooler master elite 130, but it doesn't look like it has good airflow. Is there one that has really good airflow but is somewhere around $50-80?
For airflow you are mainly looking at a Prodigy or a Node 304. Both are pretty great in this regard, and both have fairly obvious advantages with regards to their significant size difference - you can fit a lot of stuff in a Prodigy but it isn't all that compact, when the Node is a little more limited but far more "ITX" sized.
It really comes down to what you are trying to fit inside, the Prodigy is a lot more flexible, but both function very well with tower air coolers, motherboard dependant.
