Amusingly and appropriately enough, the wave of silence-oriented enclosures that have been popping up recently haven't really drawn attention to themselves as a trend. Yet all of a sudden, we have results from a couple of solid contenders from Nanoxia and a few less expensive (and more readily available) also-rans. For a little while, this was a wave that Fractal Design was riding high, but the Define R4 wound up being a little underwhelming. As it turns out, they might just have something better lying in wait.
