Can't wait, Dave. A close-up picture of the black one would be nice as well.
I found any improvements applied directly to the source component greatly improve the sound, compared to other tweaks. And the Mac Mini loves tweaks, from what I found! Couldn't be more happy with the Mac Mini and it seems every few weeks when I discover another tweak it makes my smile that much wider.
Loving that Mac Mini power cable you made, works wonders. 
Dave's MacMini products are terrific. I have the power cord and the MacSandwich and they both make the system sound noticeably better.
We're finding that although the MacMini is a computer, it acts like any other front end (CD Player, etc), when it comes to power and vibration.
Dave's power cord is a huge improvement over the the stock cord? If you wouldn't run your CD player on its stock cord, don't run the Mac Mini on its stock cord.
The MacSandwich surprised me. I didn't think that would help much. I already had the MacMini up on spikes after all. But, I was wrong, and happily so. The MacSandwhich tightened up the sound. The soundstage got wide and way deeper in my system.
Pi Audio Group's done it again...
