I didn't see a Windows Home Server forum, but I thought that Vista might be closest. My question: I want to build my own and from what I can see it is a OEM license only. I take that to mean that once installed on a computer that it cannot be moved to another machine if the original computer dies (motherboard), your license dies with it? I'd like to keep the server software and then transfer it to bigger and better machines down the road, but I assume that I'd have to buy it again?
