Well, more delays affecting the completion of this build.
Firstly, after receiving all the new Alphacool compression fittings and tubing, I tested the fittings in the blocks and had some concerns. The o-rings are very small on the fittings, and also retained in a groove. The MCW30 and MCW60 are designed for larger o-rings and have their own retention groove. as such, it makes it difficult to tighten the fittings far enough to provide a good seal. Also, the o-rings will not sit on the flat surface provided by the blocks required to provide a good seal.
Here's a pic of the o-rings that were pre-fitted to the various fittings I have:

From left to right (largest to smallest), we have:
1. Swiftech standard plastic fitting supplied with MCW30 and MCW60
2. Swiftech standard metal fitting supplied with Apogee GTX
3. D-Tek G¼ ½" fitting
4. Alphacool G¼ 10/8mm compression fitting
To give you an idea of where the o-rings will sit on the MCW30 and Apogee GTX, here's a couple more pics:

As you can see, the o-rings will try and seal against the screw threads and not the flat surface where they are intended to seal. Bottom line is that I'm not comfortable using these fittings with any of the blocks I'm using.
In addition, I couldn't get the 10/8mm tubing to bend between CPU and NB block without kinking. The coils I ordered were not suitable, and the only ones I can find are the metallic type (which I really don't want to use).
So, as a result I've decided to go back to the Tygon black ½" tubing.
However, this doesn't fully explain the delay as I have all the components required to complete the build with the ½" tubing (except the coils which are probably not necessary). This comes back to the choice of using the black tubing. I decided this week that the overall look will be odd if I don't paint the interior black. Also note that I saw
SiNiSon's Murderbox on the Water Cooled Case Gallery and was blown away. So, I've given the chassis to a friend and he's going to paint it matt black :D
I expect to have this back on Thursday and with any luck I should also have the coils by then also.
