I'm building a PC Jukebox and I've decased the PC to install in in the Juke Cabinet I'm building

What do they call and where would I find a PCI extension (cable??), so I can mount the video and sound cards remotely?

Also, do they sell the female connecters that plug onto the header pins for the on/off switch and boot switch? (is there a name for those too?) Where would I buy them?

Links would be helpful if anyone has bought from a particular company.

Thanks guys!
