Ok so my antec 1000 watt psu is great the only problem is the 8 pin connector that goes to the mobo is small in length so i can't run it through the back of the holes in the case,any place i can purchase a longer one?

Here's one:

So i can unplug the one from my psu if i want to right and run this to the male or female molex right then into the mobo?

The cable I linked is an extension for the EPS 8 pin line. I don't really like extensions, however, it's probably better than using a molex to EPS converter cable.

Basically, you'd just plug this cable on to the end of the current EPS one, so that it can reach.
