Modular computer assembly having system circuit module and peripheral circuit module

A modular computer assembly comprising:

• a peripheral circuit module including a first housing half, a connecting circuit board mounted inside said first housing half, and peripheral interface circuit units mounted on said connecting circuit board, said connecting circuit board having peripheral interface connectors to connect with said peripheral interface circuit units, and a mother board connector mounted thereon, said mother board connector being electrically connected to said peripheral interface connectors;
• a system circuit module including a second housing half, a mother board having an insert edge insertable into said mother board connector to establish electrical connection with said peripheral circuit module, said second housing half complementing with said first housing half to form a computer housing;
• and
• fastening means for fastening together said first and second housing halves, wherein said mother board and said peripheral interface circuit units are perpendicular to said connecting circuit board, and wherein each of said first and second housing halves includes a first wall and a second wall right-angled to said first wall, said first wall being broader than said second wall, said first walls of said first and said second housing halves being substantially parallel and said second walls of said first and second housing halves being substantially parallel after said first and second housing halves are assembled together to form said computer housing, said connecting circuit board being mounted on said second wall of said first housing half in parallel therewith, said mother board being parallel to said first wall of said second housing half.
