I do have a mid-tower and its quite bulky and heavy to carry if needed. I don't want a big empty box anymore. Modern components have gotten so efficient that I don't need large ATX power supplies and 14cm fans anymore.
One more case I've found is the Geeek A50 for 90$ but it seems out of stock now (and I don't like plastic sides).
