How about this. I know pipes will block overall air flow, but I do have a full tower and not alot to produce heat. Maybe a dedicated vacume pipe for my gpu or just a pig one for my row-o-pci-slots. Then I could make one for my RAM.. I smell perhaps (not burnt cpu's) the birth of a pipe machine... any thoughts on putting tons of cooling and heat removal pipes in? I think I like the idea. Taking care of each heat source with its own heat-removal vacume pipe. What do you think?
