Dirk,
  The only reason for using copper tube in a larger PVC or similar
insulator pipe is so that you can easily blow air over the gaps. There is
no reason why you can't make a linear arrangement and blow air through those
gaps. I have use this arrangement with a couple of 80mm fans and It worked
as well as any other gap arrangement I have tried.

Hi Dirk, Derek, All,

    The "pipes in a tube " system has, IMO, several other advantages 
over linear.

1) Compactness - The PVC tube has a smaller footprint.
2) Less UV in your eyes - The PVC tube is a UV light shield
3) Insulation/Safety - Less HV stuff exposed to dirt, drinks, dropped 
tools or hardware, and bits of wire, all of which are attracted to 
the small spaces between the tubes according to Murphy's Law ;-)
