Disclosed is a housing and frame assembly for electronic apparatus in which the housing comprises two identical pan-shaped members which embrace a central, generally planar, structural support member. The two substantially identical cover members are arranged for either permanent or snap fitting engagement with the planar frame member whereby virtually instantaneous access to the electronic interior is available by snap removal. When assembled complete, the frame member and electronic assembly are virtually suspended with the sandwich-like structure for shock protection. When removed from the cover and base, the frame member is self-supporting whereby the electronic assembly may be manufactured or maintenance work may be performed to all sides of the electronic assembly without interference from its enclosure.
