Embodiments of the present invention pertain to sealing an enclosure for a disk drive form factor. According to one embodiment, material is removed from a base casting for the disk drive form factor to enable insertion of a component. The removal of the material results in a portion of the base casting being thin enough to potentially cause an inadvertent hole in the base casting. A hole is purpose created in the base casting to avoid development of the inadvertent hole. A seal is used to cover the created hole in a manner that allows for insertion of the component.
