I have a iMac 450 DV+ and I want to use it as a media server with an upgraded hard drive. I have a ReplayTV that networks very nicely with OS X, but has limited hard drive space. I would also like for it to be in a cool case that I can put in with all of my home theater stuff. I have shopped around for a vga -> s-video converter and they seem to be a reasonable way to use my tv as a monitor when I need to (if I can find a cheap one). Does anyone have any ideas for this mod?
