All the cables are modular, including the mandatory ones like the ATX cable. The reason Silverstone does this is because they also sell a short cable kit for their power supplies. Ever tried to pack a really long cabled power supply into a M-ATX case? It isn't easy, is it? The Silverstone short cable kit is made specifically for short towers and M-ATX cases and gets rid of all the slack or bulk left behind from the longer cables. I personally love this accessory, partially because I'm a cable neat-freak in all my computers. The smoother the airflow, the lower RPM and quieter the fans I can run!
Cables are as follows:
1 x 24 / 20-Pin motherboard connector?550mm?
