Planning what's the best way to streamline Mobo 4pin?

I found a site::
http://www.hardware.info/productdb/bGRkaZiTmJfK/viewproduct/Corsair_TX750W/
that measured the shortest wire to be 24" (or 60 cm) to 35" so good news! I can run the cable behind the tray without getting extension or solder. if i am wrong, i found some good 6$ extensions on newegg.

Since i will be using an antec p180, i might turn this to a small case mod project log.

Thanks guys for your help =]
