Sounds good. Do you use virtualization, too? I can't decide between  
Xen and KVM.

The specs of the mainboard sound very promising but it seems to be  
out of stock in Germany and probably won't become available anymore.  
No price comparison tool has listed it at the moment.
Does anybody know if there is another mainboard out there which has  
nearly the same specs?

Regarding the clients: Do you already have some cases in mind? I like  
the Origen S14V a lot but it's fairly expensive.
