Going to grab this valve here, I need some sort of fitting though to connect it to the Magic Cube. Any idea which fitting connects it?
Most connectors are G1/4, even if they specify metric for the tube fittings. G1/4 is the size and thread that goes into the component. When it says 1/2" or 12mm or something, that's the size of the tube that's going into the fitting.
So Primochill use imperial measurements and you can't mix and match imperial and metric, because 1/2" is 12.7mm. If you have a 1/2" fitting and a 12mm tube, the tube will be undersized and leak. Or vice-versa, the tube will be 0.7mm too big (at least with hard fittings - it doesn't matter for soft tubing so they all specify imperial measurements too). Primochill fittings with Bitspower rigid tubing won't work, for example. But they all have G1/4 connectors to components. The only thing that has to match are the tubing and fittings. Any adapters, valves, etc. should all be G1/4 fittings.
So if you have a Bitspower valve or a splitter or something with G1/4 and a Primochill fitting then they will work together because all that matters is the G1/4 part.
Solid advice by Falcorambone. If you do take your CPU block off, make sure you clean the waterblock as well as your CPU and reapply a fresh, uniform, coat of thermal paste.
The best spot for your drain port is the lowest point in your loop AFTER the pump (this is so that you limit the chance of your pump running dry, which will damage it very quickly).
Since you have a pump/res combo the most logical spot is right at the out port of your res (as stated by falcoram).
You can use your own judgement, but from the pic it looks like either a "Y" or a "T" splitter will work.
When you do add the splitter, do consider adding a drain valve. You can connect it directly to your splitter (with a male to male adapter), however, in my experience, adding tubing that comes off the splitter to your drain port/valve gives much appreciated flexibility when you do drain your loop.
One last thing: you don't have to worry about draining your entire loop =). Your radiator is most likely going to remain full, which is totally fine. If you run into issues where you cant get some liquid out of a tube, turn your pump off and let it settle before turning back on as well.
