Power Strips and cables

[canon at nersc.gov]

Greetings,

I was curious what novel ways everyone is
powering rack systems.  I'm mainly curious about
high density (1U) systems.  We currently are
racking 32 nodes in a rack and using 4 20A,
vertically mounted power strips.  I'm concerned 
that next wave of machines will be too deep to 
accommodate the four power strips.  What is everyone
doing for these types of scenarios?  I don't
need remote power management at this point.
I'm more concerned with just fitting everything
in neatly.  Also, I've seen custom power cords
that clean things up.  Does anyone know a vendor
or supplier for these types of things?

Thanks in advance,
