A spring-loaded or springy biased platform for support of the components carried with a case, such as to hold a portable computer or other device so that, when the case is closed, the computer or other device is securely held within the case. In addition, a foldable shade comprising foldable segments is placeable fully within the case lid and deployable when the case is opened with end portions of the segments extending into a bottom of a bottom shell so as to enable shading of the computer screen from light ambient to the computer when the portable computer is secured to said platform. A novel connection between the case and a light stand is provided, including an improved set screw attachment. Furthermore, the computer is secured to the top surface of the spring-loaded or springy biased platform by hook-and-loop fasteners (e.g., Velcro® fasteners), the platform has openings in it to provide ventilation. Brackets in the bottom surface of the platform enable a battery to be inserted within the brackets and to the platform. Included also within and attached to the bottom of the case are such components as a power supply and an external hard drive and associated wiring.
