Trim it down to one of each cable. You don't need a half-dozen patch cables. That weird wall-wart with the proprietary DIN plug for the laptop you no longer have, or the voltage- and milliamp-specific application you'll never need. The 4 SATA cables...etc.
Pare it down in order of likely need. You might need a couple USB cables and maybe a couple SATA cables, but you don't need 3 34-pin floppy drive ribbon cables.
