looks nice, two suggestions:

1) KISS. Make the front and rear identical, similar to this image. might not rack as nicely without bottom/top/sides, but allows clean 3-wide builds
2) Re-design it so that 3*120mm fans cool 8-10 blades packed more densely. This would be terrific for those underclocking to 150GH/210W.

Completely agree on KISS principle.
However:

1) Where will the PSUs go? My goal is to have an "enclosure" to help with cooling of overclocked units.
If they are underclocked then we don't need all of those extra fans.
I have 3-wide (6 blades) design ready, although my goal was to increase density.

2) I can fit 2x120 fans on the rear wall with 2 PSUs or 6x80mm fans with same.
Unless some 60W 65 Db 120mm Delta fans are employed I can get more CFMs with 6x80mm fans than 2x120 with less noise and less power consumption
If only one PSU is used (lets say 8 underclocked S1 blades and 1 PSU there's still no space for 3 x 120mm fan in there.

As far as the number of blades, it is geometrically impossible to fit more than 9 blades in 19" wide space without modifying heatsinks or loosing side walls.
Not very clean as you mentioned
Now, if we go to 7U it is possible to mount 18 blades so that would give you 9 S1s in 7U space.

Also, the PSUs can be mounted with intake facing inside to help remove hot air.
That would simplify side wall.
However, I am concerned with PSU getting 45+ degree (C) air from the blades and getting too hot to maintain adequate output.
If the units are underclocked then this would work.

its also good to keep in mind that (from the KISS angle) a lot of S1 users that may be looking at undervolting for a higher density (such as 8 blades in a 19" space) and using server power supplies which can be operated on other shelves or have 2-4' leads (appropriate gauge for the length/amperage of course). The 1_1_1_1 photos in the pictures thread are a good example, where he has a crammed-looking setup of 3 S1 units jammed side by side in a 19" width. with 4 units undervolted slightly on a custom front/back plate it could be a slick and easy setup.
