I have been sleeving all day and got hung of the basics. Now problem occurred, i got P&C Silencer 750 Quad (Black) PSU and the 24 atx main cable is white. i found this from the depts of internet ( http://www1.acryan.com/_connectx/ACR-CB4968.shtml ) but didnt find any shops in finland that sell those. And i definetely wont use the white one.
P&C Replied to me : "Comment: Hello Niko,

Unfortunately, all of our Molex connectors are white. You can purchase black ones online, but I cannot determine if there are any retailers in or near Finland.

If you have a Molex tool, the operation should be very easy. As long as your power supply and its function is not damaged, your warranty will remain valid."
so no help from there. Im pretty stuck at the moment cause of this. Good news is my Stacker came from powdercoat ( was cheap ) and looks good.
