After buying a new case with multiple fans I decided that the standard ribbon cables were restricting smooth airflow. The answer was to replace them with rounded cables, but which ones? There are many options; black, blue, yellow etc. but these are more versatile for lit cases since the silver coloured shielding reflects light (to a degree). They have a clear plastic sheath which stops any possible electrical shorts. The IDE cables come in 45cm/90cm lengths and the floppy cable is 30cm.
