Yeah thats a piece of cake, use the same sleeving material that you will be using in the PSU cables. The SATA plugs are fairly easy to get off and then do exactly the same. Do you mean the SATA plugs on the PSU or SATA cables for HDD? Either way it still works. As for the IDE cable, that may get a little messy...but as long as you have a system whereby you mark the schematics of which wire goes where in the plug you should be fine. Are they round or ribbon IDE?
