Me likey alot.

Few things I would believe making your idea sell better:

Remove front HDD placement and have HDD holders much like seen in TJ07's at the top and bottom (ie 4 at the top and 2 at the bottom). Easier to market to server / enthusiasts who have much more HDD's (ie me with 10).
Have the front extend down with bays - personally I'd only ever use one for the DVD drive, but others have bay reservoirs, sound card front modules etc.
Ability to have PSU mounted at the top and bottom.

Personally I would love to see a wider one where I can mount the radiators at the top and bottom and still be able to mount a HDD cage infront of the airflow. Kill two birds and still have awesome storage capacity.
