Installed a 250G hard drive bought for $50 from Woot in my home server and set it up with the D-Link DSM-320. I can load it up with video, pictures, and audio and stream them all to the overwhelming HDTV of doom at a moment's notice. Freed up gigs and gigs of space on my laptop, too.
There's room for tons of content there, including a complete mirror of my music collection (almost 7000 songs) and as much video as I can stand to pile up. I wonder how long 250G will seem roomy?
