From their IT company:
It will run dual Xeon processors, about 12GB of Ram. We'll be doing a RAID5 array with about a terabyte or so worth of drive space. Also looking to run Windows Small Business Server 2011 on it and I'm wondering if there are any issues with running that. It's a 64 bit operating system. Not sure if that will cause a problem or not. If you have any questions, let me know.
