I was a part of the beta for home server; after loading it I never played with it which kind of defeats the purpose I guess....by anyway, MS did say they would sell OEM versions. when it's released, you should be able to buy the OS and install it on your barebone machines. the deal with home server though is you don't really log into that machine it runs on, it is actually supposed to run headless and you install a client on any other PC you want to connect to it for accessing music, pictures, movies, etc.. I don't know how well this will be received by new users, who will expect to sit infront of these machines and play with them; if that's what the end user wants, then I recommend a PC with Media Center Edition on it and not Server 2003. Even though Home Server is based on Server 2003, MS has added new features you can't/won't see in the plain old server 2k3 OS; driver support is lacking for server 2k3 because it's not meant to do anything other than business related activities - not entertainment type tasks. I'm starting to ramble so I'll wrap it up; use Home Server if you like, but do some research. your other alternative is the Media Center OS (which under Vista is Home Premium now), and not server 2k3 OS. any other questions let us know. good luck.
