For those of you like me running Hyper-V, there is a VPC with the some of the 2010 “IW” stack loaded:

- Domain Controller
- MOSS 2010
- office 2010
- SQL 2008
- fast Search
- Project server
- Communicator

I’m going to see how easy it is to put PowerPivot on the VPC image…

I’ve just started to download it from here
