IME there has been no difference sonically whether PC's were touching or not, and certainly didn't hear a difference if they were touching in parallel, perpendicular etc. I try to keep mine off the floor and away from speaker cables and interconnects, after that just try to be as neat as possible.
FWIW one power cord to a monoblock is pretty much circumnavigating the power strip it is plugged into, as that's the best way considering all options.
