NZXT has itself a new full tower gaming chassis which sports noise dampening technology. It is called the Whisper and when it comes available next month it will cost you around $140.
The NZXT Whisper has 10mm noise dampening foam which pads both side panels and the top panel, among other noise reduction features. There’s space inside the chassis for nine hard drives and a total of six 5.25” bays for larger expansion cards. You’ll also find inside the Whisper a pre-drilled wire management system, screwless installation and four built-in fans.
