Questions about this item

Does the metal cover assembly include the rubber feet that wear out over time?

The assembly is the complete bottom base metal cover for the XPS 15 L521x; any rubber feet attached to it are part of the piece and would be replaced together if they degrade.

What is the first limit you hit when the laptop runs sustained heavy loads with this cover installed?

The cover is a passive structural part with no active cooling or electronics, so it does not impose a thermal or performance limit; the system's own throttling point remains the governing factor.
