Home servers based on WHS are starting to be announced. Velocity Micro have "accidentally" announced their latest product, which is a pretty darn nice WHS setup.
This little beauty is supposedly "tricked-out" with SATA II, gigabyte ethernet and eSATA. It's set to launch when WHS is released and it will be accompanied by a drive expansion box in Q1 next year.
I can't wait to see more units like this.
Check out engadget's post and the Velocity Micro blog for more info.
