I have heard it is fairly easy to make a media server from older pc, using VLC or similar. Not just play spotify, though that is a use, but to set up to play movies in the lving rm or in any room in the house over a good network. Then those movies aren't clogging your new computer setup. You could even set it to be a NAS type backup storage. That wouldn't need speed or a fast video card to still be useful. Whatever you decide, good luck!
