Pros: Quiet, cool, powerful server.

Cons: Does not ship in a configuration that will permit installation of the (possibly) bundled OS

Overall Review: If you buy this from NewEgg in a bundle with Windows Home Server 2011 (Server 2008 R2 under the cover), the server does NOT ship in a configuration that permits installation of that operating system. You have to invoke the system BIOS (press F2 repeatedly while it is booting) and disable the onboard RAID subsystem. If you don't do this, Windows Home Server will fail to recognize the drive in the system, even if it is properly configured within the underlying RAID subsystem.
