So my desk setup, which I love, has...a small problem. It's an older desk with a solid built-in bookshelf back, with no holes for cords and the like. Which means power cords need to go *around* the huge desk to the back, where the UPS lives. For the Mac Pro on the floor, this isn't so much a problem. But neither Dell nor IBM decided to pack 10 ft. cords with their displays. Is there some reputable source for the generic black power cord used with...a tremendous amount of electronics these days?
