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