Where can they be had? Some OEM type plastic clam shells would be okay but something as compact but sturdier would be nice too. I considered TupperWare or such but am wary of static electricity. Likewise common plastic "project boxes", unless someone can recommend a source? Aluminum ones would avoid the static problem but in any case I do not want to enclose the drives with even semi-permanency but need to maintain ready access so screw-down lids are no good. A tight fit is essential too so as to avoid banging around inside. At worst I could resort to AS bag or box in TW but would rather avoid the "Russian doll" hassle. Suggestions?
