A blade of components for a computer system, intended to be inserted into a computer system rack, is disclosed. In one aspect, it includes a frame with means for electrically connecting to the computer rack, and a computer component holder having a plurality of through-slots configured to receive computer components translatably along the longitudinal direction of the slot. The component holder is movably mounted by means of a slide connection in relation to the frame, such that it can move between a first position in which the holder is inserted substantially into the frame and a second position in which the holder is at least partially removed from the frame, such that the vertical line of all of the slots is kept free along the longitudinal direction of each in order to allow the translatable insertion and extraction of computer components along the longitudinal direction.
