Brackets and levers for installing and maintaining motherboards in computer systems

A method of installing and maintaining a CPU board in a computer system having a chassis with closed integral sides and bottom, said chassis also having an open top, said system including a CPU board having a component carrying side facing said open top and a speaker comprising the steps of:

• forming an opening in said board so that when said chassis is in a generally horizontal position said board will be generally horizontally positioned and in which case said opening extends with its axis in a generally vertical plane,
• mounting a lever at the base of said chassis,
• causing an extending portion of said lever to extend into and through said opening,
• causing said lever to contact said board when extended through said opening,
• in mounting said lever when said chassis is so positioned, arranging said lever so that said lever can be moved in a direction to effect a generally horizontal movement of said board to position said board in operative and inoperative positions in said chassis,
• mounting said speaker adjacent one of the sides of said chassis and on said component carrying side of said board when said board is positioned in said chassis, and
• causing the speaker so mounted to be displaceable to a first operative position adjacent said board and to a second operative position spaced from said board, in which in the second operative position said board is free to be installed and removed from said chassis with the lever still mounted in said chassis.
