Note: Microsoft have also released the Windows Home Server Toolkit V1 which is available for download here.
Josh Phillips: The long awaited Windows Home Server is one step closer to being in your hands. Assuming you are a build it yourself type and aren't waiting on the uber-cool HP MediaSmart Server. You can head over to newegg.com they now have Window Home Server on sale with a shipping ETA of October 12th. For 189.99 plus shipping with any luck you will have this in the next week or so.
While I was in Redmond last week I stopped by the Microsoft company store and grabbed a copy. So I am going to try the upgrade this weekend.
