While there is a lot to like with the Zalman MS1000-HS2, there are a couple of things that bug me a little bit with this case. As previously mentioned, the lack of fan on the second HDD module makes drives installed in that bay a little too warm for my liking. Granted, many users will not use more than three drives, but for the cost of a single fan, I believe Zalman should have stepped up and provided one with this case. . .
