A computer using a passive backplane internal architecture is provided. In particular, a CPU board is provided that has a plurality of I/O interfaces (e.g., IDE, EIDE, SCSI, wide SCSI, etc.) so as to reduce the need to upgrade the system over time. However, once repair or upgrade is needed, the plug-in board configuration of the computer greatly facilitates such activity, which reduces the need for specialized (and expensive) technicians to maintain the computer. The power supply of the computer is preferably provided on an additional board within the computer. This improves the airflow of cooling air in the computer, thereby enhancing system reliability.
