Panel mount connectors for PSU?

[MacJunky]

I am planning on some cable routing/hiding, case/component cleaning, component addition/relocation, etc in my primary computer soon, and I am wondering if anybody knows a good place to get panel mount 4 pin male molex connectors as well as some panel mount 3 pin male fan connectors. I figure that while I have my primary 480w and secondary 200w PSUs open anyway I may as well make some upgrades. In this case, I want to make them at least semi-modular kinda like that Mushkin XP-650AP that SKYMTL reviewed not too long ago. (my PSUs listed in sig)

And no, I am not going to just buy another PSU as these work fine. The modifications I want to make are purely for convenience and looks.

I can't quite remember how much space is available inside based on memory alone from the last time I had them open for a cleaning. However if there is not enough room or I can't get the parts I could just fabricate a little breakout box sort of thing using parts hacked off other things and tuck it away somewhere.
