My take is they are basically the same; inside at least. Sonata Elite is described as "Two layer, steel with polycarbonate, side and top panels to deaden noise" & Antec Solo as "Dual-layer steel & plastic sound-deadening panels". They are both in the same family of cases listed here http://www.antec.com/Believe_it/product.php?id=MTk= with SOLO listed 1st & Sonata Elite mid-way down the list. Neither comes with an PSU.
