Conclusion:
I like it! Go buy it! 'NUFF SAID! But, seriously, this is one of the nicest cases I have come across to date. This is a solid case with a lot of hidden and exciting features to it.
The HDD heat sinks and the optical drive bay door that is spring loaded are features found on HTPC cases.
The muffler on the back and foam padding throughout the case help reduce the sound transmissions. There is even foam around the door on the case. That is mostly aftermarket stuff, but it's all included in the Lian Li PC-S80B, which, by the time you read this, will be available at *******-***.com.
Even if you are not in the market for a server but want to go silent, the PC-S80 is still your ticket. The overall construction is rock solid, and the installation of components is straight forward. You would expect nothing less from Lian Li. They certainly went all-out on this case, keeping the airflow good while keeping the noise down.
One other thing I almost forgot to mention is that all the edges have been rounded over or covered, so no issues with getting all cut when installing hardware. This is another fine product from Lian Li, proving once again that their name is synonymous with quality and performance that will last for a long time.
