"There aren't a lot of cases on the market that come with sound dampening material. I'm not sure why this is considering it's relatively inexpensive. Thankfully the NZXT Whisper Case does have this foam on the side panels and the top and it makes for a very quiet build. I wish they had included some on the bottom, back and front as well though. Besides this the case has a great look, lots of drive bays, a fair amount of room to work, but the motherboard tray is not removable. Watch the video to find out more..." ~http://www.3dGameMan.com
