A modular computer chassis constructed with a center pluggable interface adapted for the modular mounting of components on opposite sides thereof. The chassis includes frontal and rear regions which are open and adapted for receipt of modular computer components therein for direct coupling to the center pluggable interface. An isolation frame is also provided within the chassis for physically and electrically isolating select components therein one from the other. A slidable mounting array is also provided for facilitating flexibility in the mounting of half height and one-third height disk drives adjacent to the center pluggable interface for flexibility in the design and utilization of the chassis of the present invention.
