I’ve been running Windows Home Server (WHS) on a spare PC in my basement for the last four months; specifically, the release candidate for the first three of those months and the RTM-version for the last month. It’s become my media center storage vault and shared server, as well as my primary device for automatically backing up all of the PCs in the house. It even provides secure remote access! The product is incredibly easy to use and the GUI is very intuitive! If you haven’t tried it out yet, I urge you to do so.
Most customers will get WHS with a new ‘head-less’ (no keyboard, mouse, or monitor) reasonably-priced PC designed for WHS; however, you can purchase an OEM version from various vendors and then install it on your own spare PC–which is what I did. A number of vendors had the RTM version of WHS in stock when it was released about a month ago, but it quickly sold out. I ended up buying my copy from eWIZ for $159.99. I just received an alert from Buy.com that they now have the product in stock (again); however, it’s priced at $190.99–which is higher than it was originally. Get it at eWIZ; I received the product cross-country, via standard shipping, in only three business days!
