Looks nice.. I do think mine aren't removeable.. There is a cap on the middle ones but the end ones don't have it.
I might need to cut them off and replace them.. Any suggestions on a place to get sata power plugs than I can put on here..
Also, where do you buy your sleeving? And is it 1/8th inch? I was doing mine with various sized over the bundles of wires.. I like the look of the way you have it done better though.
