A computer case with side panel clip fastening configuration utilizing a direct clip fastening method to quickly secure side panels of a computer case to a computer case housing. An inner catch first lodges into a notch defined on the side panel, and subsequently rotated 90° therein to secure its positioning. The configuration further employs a cylindrical positioning socket configured on the clip fasteners to pass through through-holes defined in the side panels and thereupon into securing holes defined in the computer case housing. The side panels and computer case housing are thereby assembled to form a computer case in its entirety.
