I, myself, use this exact same Power Supply and I love it. The modular connectors are standard molex form factor, so the modder in me took advantage of that fact.
I purchased black molexes and the appropriate pins for the inside, and built my own cables for my unit! The modular concept that the power supplies are starting to follow is going to lend itself to some crazy/stunning cabling as people get more and more comfortable with them. I, myself, will likely never purchase another standard power supply. This one has won me over. I'm keeping my eyes on these Ultra supplies... I've heard a few things from other users... but nothing that makes me regret the use of it in my full time computer!

Now.... I like the Ultra's from a modding standpoint. Keep an eye on those power spikes though!
Good work Rob!
