Abstract: A computer system includes an enclosure, at least one cable holder, at least one data storage device, and at least one cable. The at least one cable holder is attached to the enclosure. A guiding space is defined between the at least one cable holder and a bottom wall of the enclosure. The at least one data storage device is installed in the enclosure and located above the at least one cable holder. The at least one cable is received in the guiding space. The at least one cable holder separates the at least one data storage device from the at least one cable thereby preventing the at least one data storage device and the at least one cable from interfering with each other.
