Component Cable Question

[Tom Snyder]

I ran a component cable run of 75 feet, and ended up with an extra 25 feet. So I cut off the extra and used it to do a short run between where my computer will go and media closet.  

So my raw cable is there, but when the walls are finished, I'll need to put jacks on the ends.

Any advice on which ones to use and where to get them?
