I'm going to be upgrading my rig in Oct. and will be turning my old hardware into a NAS to store my files. What I don't know is how to set up the NAS so that it goes to sleep after a few minutes of no activity and how to wake it up when I want to transfer files for storage. I figure this will save me money rather than keeping it on all the time. Can someone advise me on a guide to do this? Thanks.
