i would keep away from that thermaltake one. keep the dual raddy you have and go for this setup:
laing dcc pump. there is many different classes, some being crazy prizy (the 18W) and some being just affordable. get one of thoose. even the small one will fit you need. i have 2 18W in the same loop, and one of them can easialy handle it. if you want a pump thats not as noisy, you can get a laing d5. they are amazingly quiet.
for waterblock, i would go for a d-tek fuzion, or a xspc acrylic edge. of course the fuzion is better than the xspc, but its also aprox twice the price.
for resevoir, i would go for an xspc single, or dual resevoir, that fits into you 5.25 bays. the are handy, and looks awsome
hoses, go for tygon. they are the best to work with.
fittings, just take what suits you. ive learned that you wont gain better result with having 19 mm hoses instead of small 6 mm ones, so just take what you want to work with. the 19 mm can be hard to work with though.
for fluid i would go for feser one.
for your waterblock to the gpu i would go for a Swiftech MCW60-R Rev. 2. dont bother with a pricey full cover block. your a likely to change that card in the future, and that way you can use this block on the next card as well. you might want to put some heatsinks on the gpu“s ram though
you can get thermal tape that is sticky on both sides.
for chipset, EK is always good
so just find the one that suits you.
this will make of a rather pricey watercooling system, but i promis it will work 5 times better, and longer than the thermaltake one.
think thats it
your welcome to contact me if you need help putting different tube sizes and fittings together.
