Adding second SATA Drive

[illegalprelude]

Ok...wtf...I didnt think this would that hard but i cant figure out how to add a second SATA hard drive to my PowerMac G5. Do I need to use the cords that come with the G5 or is there already something in there cause it seems like it...

I couldnt find any useful articles with step by step pictures 😛 Anything would be awesome you guys.

I feel dumb even posting this. I can build an entire computer but cant add a HDD 😱

ok scratch that. I was just afraid on pulling on the cords. Sense they hadent been touched, they were just stuck a tad to the case but everything is good to go and im formating the 500GB sata as we speak 😀
