I called Customer Care at 1-800-624-9897.  After navigating all the prompts I finally talked to someone.  Of course I had to go through all the security questions to make sure I was who I said I was.  When I explained my issue I was told I would need to talk with the sales team and I would be transferred.  After a very long wait I was finally connected with a very heavy accent individual who said he would be happy to take my order.  It took a while to explain to him what my issue was but he then told me I  needed to talk to Customer Care.  I told him I just talked to Customer Care and they transferred me to him.  He then said he was the wrong contact and that he would connect me with Small Business Sales.  I then sat on hold for another very long time only to get disconnected. MORE ARRG!!!
We received our NX400 with Server 2008 Standard Version today.  I went online to review it's configuration and noticed that Server 2012 is now offered for the same price, ARRG!!   I haven't even plugged it yet. What am I missing?  Should I request an upgrade?
