kind of weird - it would be interesting to get some first-person commentary.
I've got nothing against wire racks, not even against somewhat messy cabling.
(the goal of cabling is to _work_, while being reasonably maintainable, etc.
labeling is great, but I've seen some _abominations_ that were very neat 
but impossible to maintain.  not to mention cables so tidily tie-wrapped
that they exceeded their min mend radius...)

the open-air cooling is also pretty amateur-looking.  I guess one benefit
of going green is that you can be sloppy about airflow ;)
