I would go with distilled and PTNuke and/or Killcoil. There really is no guarantee that the colored Fester fluid won't gunk up the loop, and temps are likely to be a few degrees worse anyway. Every test I've seen comparing temps of Fester's fluid to other common coolants, the reviewer adds crap like water wetter to the distilled water to worsen it's performance and make the Fester stuff look better, even then, it usually comes out a draw.

I understand that Triple DDC might seem like a joke to some but I'm seriously considering undervolting these to about 10.5V. Dunno how I'd go about doing that but it should definitely be quieter than two 3.25's running at 12V.
There is very little difference between all the DDC models in the term of actual noise. The biggest change, which also isn't much, is the pitch of the different models. I re-visited your OP and honestly, I think 1 DDC 3.25 would be fine with your proposed loop.

I'm also a bit confused about the whole aluminum vs copper argument. Are you saying that I SHOULD go with ALL aluminum or just all COPPER? Basically I should stick with one or the other.
If your dead set on using a part that is aluminum (such as the XSPC res), then your better off going with an all aluminum setup...blocks, rad, res, fittings, etc., just be aware that your temps are really going to suffer. How do I know?...first hand experience. I built this system a while ago as an experiment and was very disappointed with the results (so disappointed, it only lasted about 3 months before I switched it over to a real loop). I had set the temp warning in BIOS to 65°C and it would routinely go off while at Youtube watching videos. There was no OC on the CPU either. In short, your better off avoiding aluminum all together.

Copper, brass, nickel plate, gold all work well together and will give much better temps. It's also easier to find all the parts you'll need made of these materials as well.

Here's some other things I would change from your OP as well. Forget about the teflon tape, it's not meant to work with the thread style the fittings we use have. The Sunbeam pin extractor kit is junk, I have one and don't use it. This is the best ATX pin extractor tool but it's a bit pricey. This is also a very good ATX pin extractor and is a bit more reasonably priced. It can also easily be used on floppy and 3 pin connectors as well, unlike the first one. I have both and use which ever one is closest at the time. For the 4 pin molex, I use one similar to this one though mine is from FrozenCPU.
