Looking for a Mac compatible/tested NAS Synology unit?

Amazon.com: Synology DiskStation 5-Bay Diskless Scalable Network Attached Storage DS1010 Black: Electronics.  Great reviews.  For around $900 cheaper than a Mac OS X server, and could probably be set up by an experienced layperson.  Something to consider if budget is an issue in your company. You can find more details here on its compatibility with Time Machine.
