Who needs better vents? Your hot components do. Any good gaming case
are judged and rated on its performance and the majority of it comes on its
vents and cooling system. The more your case can provide proper ventilation
to cool the hot components inside your system the better those components
perform and the longer they last.
If these are the only two gaming case you prefer, then go for the one that
provides better cooling performance. If you would ask me which from these
two? I'll go for the Lancool K62 same as JohnnyLucky recommends.
But if you would ask me which are the latest and the best gaming case
that i could recommend that offers high cooling performance? Well,
based from the good reviews and awards they won and also from my
experience of setting up gaming rigs.
