What's the neatest way to do the cables on the Corsair HX1000 where they enter the PSU? On my first one, I ended my uni-sleeving about 10 inches from the end, but I'd like to take this one all the way.

I've searched through the pics here, and about half of the ones on the German threads linked earlier but still no clear idea of how to do it. Thought of taking the cover off to heatshrink into the opening, but that doesn't appear to be as easy as I thought it might be
