Windows Central posted a review on the Silencio S400 Case
A quote from the article:
It's not flashy by any means, but it will certainly keep your office or gaming room feeling like a library.Silencio S400 Case Review
Cooler Master has quite a roster of PC cases available, including the Silencio S400. It's a case that justifies its name with sound-dampening panels on the top, sides, and front, giving you a bit of peace and quiet while the hardware inside powers on. It's a fairly basic case when it comes to styling, with a black exterior and your choice of solid steel or tempered glass side panel. It's also fairly affordable, generally hovering around the $100 mark. I built a PC inside the Silencio S400 to get an idea of its pros and cons, and ultimately to get an idea of whether or not it's worth the price.
