I had a microATX case for about 5 years, and it wasn't great. I can't imagine building or using anything even smaller. I had to practically disassemble the whole thing if, for example, a fan started rattling, a SATA cable was loose, or I needed to reset the BIOS[0]. I got a much larger sound dampening case after that, and it's amazing. It's easy to work in and much quieter, and I don't mind the size because there's lots of room under the desk. [0] I wasn't using a board that was high end (or recent) enough to have a back panel button for this.
