I would recommend everything there apart from the rad.
I am in the process of discontinuing the Alphacool rads in favour of some BlackICE models instead.
And most retailers are now routinely putting RMA parts under a UV lamp as they can reject RMAs if they find so much as a splash of UV fluid on it. Some will even charge you £10 for the privilege. Some retailers are now also rejecting RMAs if you've replaced the stock cooler - and then replaced the original. They use traces of non-standard TIM to 'prove' this. All the retailers sell WC kit, but they very much wash their hands of you (no pun intended) if it goes wrong after the water cooling has been installed, even if the issue isn't the water-cooling. Using distilled water avoids the conductivity problems and it's undetectable subsequently. Using deionised is almost as good, but you don't get the same level of protection against conductivity issues.
It shouldn't taste sweet anymore. I think that by law it has to contain bitrex, which tastes horrible to almost every species capable of deciding whether to take a mouthful or not.
They are still trying to make it law

That pump is a bit weedy and the supreme cpu block is very restrictive.
If you stick with that pump consider the Fuzion v2 block or, better still, the XSPC Edge.
If you really want the use the EK supreme I would really consider getting a stronger pump (DDC or D5)
I've listed here ways in which you can choose certain products, as in my opinion, a choice on a certain part of your loop will affect what part will work well with it.
1. CPU Block - If you want to use the bay res and pump combo, going with the FuZion will help due to the weak head pressure that pump offers compared to a DDC.
The Supreme is restrictive as it uses a inpingement plate, if you want an all in one pump/res solution then XSPC do a great DDC top with a tank built in. This will match the Supreme very well.
2. Tubing - 7/16th over 1/2" barbs. I would use D-Tek or DangerDen barbs over EK as the seal is much tighter.
3. Coolant - Distilled Water with PT Nuke. Do NOT use dyes, I used to and after seeing the crap that came out of my parts after a clean up, it became apparent how stupid it is to include it.
You want to use dyes? Don't come crying to those when your impingment block becomes clogged with crap when the dye seperates (as it will do) and also when you can't clean it out of your radiator 100% fully. If you want to tear your loop apart every 6 months or less then go a head.
You've now swapped to an even weaker pump and retained the restrictive supreme.
You'll need 6 barbs and clips in total as far as i know. 2 for the rad, 2 for the pump, and 2 for the block.
Do any of the components come with barbs??
