The last PC left on my network has been relegated to being used solely as a media server which I use tversity to push media to my PS3 wirelessly. Now its been working out relatively well but I would like to be able to be rid of the PC and simply integrate this function into my Mac. Also, my PS3 only contains an 80GB HDD so its a constant issue of manually moving and erasing content on the PS3. Doing research on how to accomplish this is making my head spin with all the different ways I could do this. I also have a separate issue of backing up all the macs manually every week via a USB HDD. Ideally I would like to just add a bunch of external storage to the PS3 and stream the content once and be done, but then I'm still stuck with the PC and it still does not address the backup issue. I know time capsule would work, but I already have plenty of storage and a good router. I'm willing to spend the money on whatever I need but would like to do this as efficiently as possible with the hardware I already have if possible. Thank you for any help
