I'd go with the CM Silencio. While the carbide series look great when new, the case finish (I've found) just goes to crap pretty quick. FX's post does bring up an important thing to consider, apart from function, and thats personal tastes. While some of us may prefer certain cases due to our own aesthetics, we don't have to look at the case on a daily basis, or use its functions. You do. So weigh this heavily, just which case fits your aesthetics better. My personal taste run classical lines, so my nice square subdued fractal design r5 is perfect for me and I can't stand the wild extravagance of the Apevia X stuff, yet some love those gaudy, extreme gaming cases and think my r5 is beyond boring.
Make a list of pros and cons and then decide if you can live with the answer, or keep shopping.
