This helmet can be considered more of a novelty item than anything else. Still, with bonuses to nano range, nano resist, nano pool and Add All Def, it might find a loving home by some nano professions. Unfortunately, the Spirit of the Hooded Crow is a bit hard to come by, since it drops from Natsmaahpt, a level 250 dragon dyna in Inferno. The Nano Armor Helmet can be found as mission reward or random drop from RK mobs. It must be QL 200 or you won't be able to assemble parts.
