you will need air filters for the front intakes since they are sending air to the HDDs. there is no real fresh air hitting the HS\fan combo for the cpu, so, that may be a draw back. the drawings arent draw to scale, it's hard to recommend anything. there are no size constraints you gave, so (again) it's hard to recommend anything. it may be a bit hard to route the cables since you have so many drives, i recommend some sort of built-in cable management. and so many cables means poor circulation usually.
