I've done some searching, but all I find are ways of adapting other things to provide PCI-e power to graphics cards when the PSI doesn't have dedicated lines for this. I'm building a Hackintosh that won't need any graphics card because it's doing my home automation, iTunes, Plex and file serving. So it has lots of drives, but I won't use it to play games. Is it possible to repurpose the PCI-e power from the PSU to run fans, card readers, and the like? Without custom building a transformer, that is.
