I haven't seen your work in progress. Three things:
2. It is ironic that so many use P2P and yet you will spend all this time on servers.
3. Plus, while someone may screw up the mobo install or the processor on a client, that would be OK, but to build a faulty server would be more of an issue.
It makes question what makes a server, the hardware you put in it or the operating system you use? The point would be to get people to use server grade hardware while still using Windows 7 (if they prefer). That way, they at least have the hardware reliability of a server which is a pretty big plus. But I'm going recommend SBS Essentials because sharing files and folders is even easier than Windows 7 and it you can join Win 7 Home Premium/XP Home edition computers to the domain as well which I thought was pretty cool.
It's not that hard, you can build a computer with just a Phillips screw driver. There are temperature monitors for the CPU which let you know how well you've done and how stable. Most people run a stress test before they finish. I guided someone over skype and they built it in less than 30 minutes. And that was a full tower gaming computer.
