BurnOutPC.com has just posted a review on the Nexus DiskTwin.

There's not much to say really. The Nexus DiskTwin do a great job of keeping my harddrive a little bit cooler and my case noise free. I'm running with an Accelero S1, with no fans inside my case. It's really silent and I'd like to keep it that way. There are lots of great cases on the market that have some way of reducing the vibrations coming from harddrives. But other cases simply don't. If that's the case than this is the way to kill those pesky vibrations. Installation is easy, they look great and their cheap too. Only 10 euro's a pop
