To facilitate user installation of units in a computer, a clamping lever arrangement is provided which can be tightened by an external screw to clamp in position one or more units internal to the housing. In one arrangement, the clamping lever is provided with four fingers that pass through respective apertures in the computer housing. Each finger serves to clamp in position a respective expansion card, or blanking plate if no card is present. Thus a single clamping lever with a single external fixing screw replaces the standard usage of a respective fixing screw for each card.
