A computer tower chassis (10) has a base system unit (20) and a main circuit board subassembly (30). The base system unit (20) includes base system frame (200) having a front panel (21) and rear panel (26) and supporting frame (201, 202, 203, 204, and 205) therebetween. Disk (22), control panel (23)
A computer tower chassis (10) has a base system unit (20) and a main circuit board subassembly (30). The base system unit (20) includes base system frame (200) having a front panel (21) and rear panel (26) and supporting frame (201, 202, 203, 204, and 205) therebetween. Disk (22), control panel (23), power supply (24), and floppy drives (29) mount to the base system unit (20). The main circuit board subassembly (30) includes main circuit board (31), input/output board and cable (32), speaker and cable (33), fan assembly and cable (35), keyboard cable (36), expansion card (37) and expansion card guides (38) and (39). Main circuit board subassembly (30) fits within and adjacent to base system unit (20), with chassis cover (40) surrounding both modules. The modular design allows for safer and more efficient manufacturing and handling.
