A direct-contact liquid-cooled (DL) Rack Information Handling System (RIHS) includes liquid cooled (LC) nodes having a chassis received in a respective chassis-receiving bay of the rack and containing heat-generating functional components. The LC node configured with a system of conduits to receive direct contact of cooling liquid to regulate the ambient temperature of the node and provide cooling to the functional components inside the node by removing heat generated by the heat-generating functional components. The chassis has a leak containment barrier configured with a trough that underlays a portion of the system of conduits of the LC node and that forms a drain path to a drain port of the chassis. In one or more embodiments, the storage drive carrier has vibration absorbing material that mitigates vibrations of a storage drive placed in the storage drive carrier.
