I'm currently installing Windows Server 2008 R2 on a newly built computer. The system does meet the minimum requirements. It seems to take forever on the "expanding windows files" section. I've left it run for an hour and it hasn't moved beyond 0%.
A test shows that both Windows XP and Fedora 10 install successfully on the same system. The Server 2008 R2 is downloaded from Microsoft Dreamspark.
The system has a Core 2 Quad Q8300, and 2GB of RAM.
