That's better, I like this a lot more than the 600, even after losing the 5.25" bays.
This case in general, but especially outward design reminds me a lot of the Fractal Design Define S. I like the single top panel cover better than the somewhat annoying overlapping 3 piece cover that the Define S uses. Similar designed front panel, similar location for the front panel, similar dimensions albeit a little smaller). On the inside is where the mix up to me starts. The two cases also swap physical capacity numbers; the 400Q can hold three 2.5" drives and two 3.5" drives, where the Define S can handle the reverse at two and three respectively. particularly the location of the 3.5" storage. As the 400Q has them horizontal on the bottom, that will no doubt be more familiar to case builders, placing the 3.5" bays here does have ramifications .
As mentioned in the review, with the parts used in the build "the 400Q is just begging for a large front mounted radiator." This is one thing the Define S has a distinct advantage. Since the Define S mounts it's 3.5" drives vertically with the 2.5" drives behind the motherboard tray, it allows for a nice and thick 360mm radiator, something that the 400Q can't do without sacrificing storage capacity. If you were to go top mounted, the Define S similarly gives you more options, but that is due to the design of the top panel and not having something "in the way." If extensive liquid cooling is in your future it would be harder to argue against either case, but the Define S gives you more options in that regard and probably at the same price point of $70-$80.
