"Get the $999 version instead"5.0 starson by theveggiedude
Pros: Comes with OS X server software
Cons: No cons, the hardware is FREE when you consider the OS server sofware is $3000 for Windows equivalent.
Summary: The $999 version comes with OS X server software, which outperforms Windows Server (38 minutes downtime vs 2.5 hours - http://*******.com/yjeujmf). Based on this alone, it is like getting the hardware for free, as the Windows equivalent software alone is $3000 for 5 users only. This allows unlimited users.
