Thanks for the responses. Someone else has also pointed out to me that the driver base is the same although it is nice to have several people confirming the same thing. One last point regarding drivers and Windows 7, would it better to install the 64 bit version of Windows 7 or the 32 bit? I would assume the drivers for server are only going to be available in 64 bit and better supported these days anyway. Thanks.
Has anyone tried and been able to install Windows 7 (workstation not server version) onto a PowerEdge  R210. We are currently looking at purchasing one to replace a PC that does various tasks on out network, however we really don't need a server OS on it. If anyone has had success with this which drivers were used? The intention is a basic system with no RAID or addon cards just to use the onboard controller with one hard drive. Ideally we want to be able to use both the onboard NIC ports too.  Any suggestions or inisight would be appreciated.
