Shorten those lengthy power cords?

Consider resale (if that day comes) otherwise go for it.

Xt16,
I'm thinking of just doing the ones that are detachable,
therefore replaceable.

If these are just standard computer iec cords, nothing special, it may not matter what plug you put on them. If you plan on doing DIY later down the road and making some better cords, go ahead and buy the expensive plugs - you can always use them again when you make your own cables. Just saying, as long as you are buying the parts, you might want to make some DIY cables.

That's a great idea Peter. Any information on cable that is recommended?

A little different advice here,try to keep the power cords away from your interconnects.Also try not to run IC's and PC's parallel to each other.Power cords down one side of stand, interconnects down the other will help. The power cords could have radio frequency plus other bad noises in it that the IC's could pickup and degrade you music.
