Server 2008 is supporting DX 10 and is faster than Vista, thats the point why i want to use it

After a few settings, you can use Server 2008 as a Desktop environment.
You can use the Desktop-themes-service under Server 2008 and apply the Vista-Theme (thats why i hope that WindowsBlinds will work)
A secound point for me is that i am not owning a copy of Vista and dont want to buy (not now) it. You can download and test Server 2008 for 240 days, thats why i want to give Server 2008 a chance ^^
I will try it out tomorrow...
