Without changing the hardware this basically means move stuff from your
10TB of local disks to the NAS.

The local RAID is required for uncompressed HD video editing.

You want the air to have to travel in a zigzag pattern so that there is no
direct
path for sound to escape.

I was thinking along the same lines, but check out the 3D Model Tour at
http://www.kellsystems.com/3d.asp#tab9

It appears the air intake is at the bottom back of the unit, and the air
exhausts are a relatively simple modular package at attach to the back of
the unit.

The way I interpret that video is that the air intakes are at the bottom
and top but near the front. (They advertise "front to back airflow" in
the text".) The exit is at the back.

For a tower enclosure I'd just do intake at the front and exit at the
back, but with zigzag passages lined with sound absorber panels. If
you've got carpet it may be beneficial to orient the openings facing
downwards to get a bit more muffling effect. You probably want the
enclosure to fit fairly snugly around the side of the tower to avoid
warm exhaust mixing with the incoming cool air.
