That's why we <shameless plug> offer the design services and will be 
offering these units to integrators soon. (/shameless plug>

I wouldn't add the extrusion to the 1U enclosure, I'd replace the top 
half of the enclosure with it. Then you'd still have the 1U profile with 
a lot of surface area for convection cooling. A 1U with a nice extrusion 
for the top half would be less than $50 in materials and labor. This 
would work well unless you're building nodes with CD-ROMS, RAID and 
other high profile components, but how many nodes need this? maybe 1?
