Zalman Z9 Plus Case Review
 

After examining the Z9 Plus chassis, I was very pleased to see that Zalman has addressed the vast majority of the issues I had with the Z7 series. Not only has Zalman improved cooling performance while still keeping noise in the acceptable range, they've given the interior a matching black finish for a uniform look, updated the aesthetics and added support for a couple of SSDs as well.
