ABSTRACT:
Using a relatively simple four piece conversion kit consisting of a replacement control bracket, and vertically enlarged top housing portion, drive bay and expansion card cage replacement structures, a relatively small frame personal desktop computer is converted to a larger frame computer having upgraded expansion card and drive installation capacities. The upgrading process is effected simply by removing the existing top housing portion, drive bay, expansion card cage and control panel bracket, installing the replacement drive bay, expansion card cage and control panel bracket on the existing bottom side portion of the computer, and then operatively connecting the vertically enlarged top housing portion to the existing housing base wall. Other than the four components of the conversion kit, all of the components in the original computer are reused in the resulting upgraded computer.
