Thanks Justin.
So now my question is why you need a server. Why not just network your machines like mlange is doing?
Well, I've been running Windows Home Server for some time now and it works OK, but I like the idea of having a much smaller device that draws less power on all the time. Having a server with all your files on it is powerful in so manys. Access for friends/clients to FTP their files to you/from you. Serving up a blog or photo gallery - with Synology's box you can have up to 30 distinct virtual web sites. DNLA server for my Logitech revue - so I can watch videos, photos or listen to music. Iphone connectivity so I can browse all my files on my iphone. Itunes server. I like the Mac connectivity for Time Machine. Mail server so I can keep my email centralized in one place from multiple sources. Hook up an wireless network IP camera to it and I can monitor the front of house wherever I go - even on my iphone. And the ability to configure and control it all from any computer connected to the internet. It's just cool to get this from a low power device instead of leaving 1 or 2 computers on all of the time.
