I have a MediaSmart Server (MSS) that I was able to hook into my first generation Touchsmart for backups, in fact, it backs up all of my PCs in my network.
The really cool thing about the MSS is that you don't actually have to put any of your media on the TouchSmart if you don't want to. Just put it on the MSS and access it from any of your PCs around your house including the Touchsmart, then you don't have to worry about duplication of media files and keeping duplicate folders in sync.
There's many other benefits too, which you can read about on MediaSmartHome.com.
