Replaced my Densium 4+ V2 case. with the Cook MQ5. It was a trade off between longer GPU support and better cooling respectively. Though the build quality was similarly good, the Sparrow MQ5 felt more premium with that one piece milled aluminum construction and magnetic steel side panels..
The MQ5 comes out cheaper starting at $199 with a gen3 riser cable vs the Densium 4+ without a riaer at $195 exclusive of shipping at the time of writing.
Between the Densium 4, Velka 3, and MQ5; The Sparrow MQ5 is in the goldilocks zone of size, compatibility and thermal performance.
