It's very roomy and I like that, you could probably put some E-ATX inside. Build quality is, you know, Cooler Master. While feel like unfinished product it still quite good. If you use ODDs you can't use the top bay because screw hole on the left side is covered (which is exposed in older version). Airflow is decent, front mesh somewhat useless because you got big hole at very bottom. No rattle, not sure about pop off plastic because mine is good enough.
