A multimedia storage case structure comprises a case and a holder mounted within the case. The holder includes an elevating base and a snap boss thereon. The elevating base has first and a second resilient lips that are separated from each other via a plurality of grooves. The first and second lips bend toward a center of the holder and protrude upward to form the snap boss. A first portion of the snap boss, connected to the first lip, includes a claw and further bend toward the center of the holder to terminate in a top pressing cap that centrally overlies the snap boss meanwhile being spaced away by a gap from a second portion of the snap boss connected to the second lip.
