I was impressed with Tranquil PC's Windows Home Server when I saw it at Microsoft's Vista After Hours Event a couple of months ago. I was even more impressed when I found out Tranquil are based about 5 minutes down the road from my office in Manchester. Tranquil have kindly lent me an evaluation version of their fan less 1TB Windows Home Server for me to do a video review. The first thing I noticed when I picked up the unit is how small it is. For a 1TB storage unit it is tiny, see this picture below of the unit next to my Xbox. So fitting the Home Server in with your existing equipment should be no problem. All it needs is a network point and power.

More info on the video review which should be out soon and I have an interview with Tranquil on The Media Center Show soon
