There has been a slight revision in our casing that we had neglected to previously explain.
The case has had an airflow improvement to ensure increased thermal efficiency.
We have ensured the hot air from the front two heatsinks is redirected, avoiding the rear chips, and is expelled from the casing by installing fins affixed to the upper casing section (despite appearing in the CAD as part of the lower section of casing). In turn this allows a sufficient amount of cool air exits to ensure a cooler operating environment for the rear heatsinks to operate comfortably.

I agree with the linear idea but at least they started thinking about thermal airflow now. I just wish they had started sooner like when I first mentioned it looking at the CAD pics.
OK, just been thinking about this problem for a bit and my best idea so far is to use a "double-decker" design. 2 hashing units, side-by-side, with the other two sitting on top. Allows for a cube type case, allows 4 intake fans (or perhaps just one big box-fan) and a very simple, straight-through airflow. Might not fit in a standard rack but it's incredibly more efficient and clean design.
