dell dimension 4600 case changing

hi i'm new here, so i want to change my dell dimension 4600 case, yes i read about rewired wrong and stuff, i've already got a new PSU and a new graphics card and now to change the case, i was wondering if anyone had diagrams on the wiring of... how can i put it, wiring of the pins that are connected to the boot/reset button at the front, if im correct its about 10 pins but i need to know so i can get the corrent wires so my new case will boot the system.

Thanks
