First loop water cooling component and setup advice needed

first what case do you have
res is good
if you want to they make a pump adapter to attach the pump/res .
if you haven't bought the tubing yet get 3/8 5/8 , 3/8 1/2 since 1/4 is the smallest tubing and it has some compatibility issues
rad i have never used swiftechs rads at all. recommended ek xspc and watercool for there rads since there the best .there cleaner then some of the rads/companys that make them
that cpu block should be fine never used koolance's for blocks
for the 970 check your card version since if you dont have a 1.1 it will not fit i had a 1.2/1.3 and it didnt fit either card . dont know if ek has updated there block i got mine about 3 months ago . just to check you have the red shoud one correct ? some also come with the yellowish green cooler's insides which is a insta giveaway that you have the wrong version. i had to return my card 3-4 times till i got the 1.1 version. they have a different layout even
coolant distilled is fine dont put too much pt nuke in before you assemble your loop flush all the parts out first

for the fittings this is where the fun starts. fittings can end up costing equal to all the other parts combined if you want 90's and 45's and male to male connectors . there is also the brand bitspower is the most pricy but there also the best out . there are dirt cheap compressions like perf-pcs has xspc ones for 4$ each . i buy mainly ek's and alphacools since they have the colors i wanted .

fans ek's vardar are good so are gently typhoons ek's fans are about 15$

i mainly stick to ek for there blocks/rads/fittings/pumps xspc for the rads bitspower for fittings/res's
for pumps that one is decent but i perfer a d5 since i have the room
[strike]i tried to find the restriction on that block but google doesnt want to help ive seen the dam thing just cant find it will update here if i can [/strike] it was the performance that i saw here it is http://www.overclock.net/t/1505481/lightbox/post/22655918/id/2266977 lower is better and its a bit old 2014ish
