In the future I'm sure you'll wish to go with a single box like the Western Digital Sharespace:

I'm waiting for prices to come down on the 2TB drives and especially the networked storage boxes. I'm willing to pay up to $300 for a networked storage device and $125 per 2TB drive for about $800 total.
I want something that I can access remotely, but mainly it's for sharing DVD/BluRay rips (mine of course) and other video through the network. I keep looking around for an easy and cheap way to build one using something like the ATOM.
Consdering the fact that I also want a device for each HDTV to actually play the content maybe I should construct a Home Theater PC that also serves as my Home Server. In this case, maybe a dual-core ION solution (the REVO with 330 ION looked interesting spec wise).
I did the math and my DVD collection (and the, uh, rest of the video) is over 6GB. At about 20 minutes per disc the prospect of putting all these DVD's on my hard drives is another issue...
