I have the server now for quite a while in use and am very satisfied. My equipment is the standard machine with 256 GB HDD but with 8GB of RAM. For me, a Citrix XenServer, which provides 4 virtual machines running Windows 2008 Server available runs. About dynamic memory all the machines between 1.5 and 2 GB of RAM and two virtual CPUs have. The CPU load on the server never goes above 80%, even if the virtual server have the right thing to do. RAM usage is of course consistent at 90% but this is felt not by higher volume even by mistake. The server runs in 24-hour operation and has the right thing to do by virtualization (that would have to do more than he in every household). I'm going to replace my whole DIY projects now gradually through the MicroServer. Very strong buy recommendation.
