need help with water cooling

[ninjapuppy114]

Im building my first pc and im thinking about water cooling. I know the basics. If i do i will be cooling my cpu (intel core i7 4770k) and my gup (NVIDIA GeForce GTX 780). I will be overclocking both of them. I just have a few questions

a) will other parts of my computer get hot? How do i fix this?
b) What order should it be in, reservoir to pump to radiator to cpu to gpu. or do i need another radiator in there?
c) how big should the radiators be?
d) any good kits for this? or good parts?
e) how much will this cost? is it worth it?

This will help me a lot if you answer these. Thanks

a) Nothing else should get too hot. Only the CPU and GPU should need active cooling. If it doesn't you have a faulty product
b) In terms of order it really doesn't matter at all, the only thing that matters is the pump has to come straight after the res otherwise it might dry out and break. Apart from that it doesn't matter
c) If you're overclocking both I would go for a minimum of a 60mm thick 240mm rad for each part, so two. More is better though, also more expensive
d) There are some good price v performance kits out there. I like the aplacool Cool answer 360 kit myself, it's a decent starting point. However getting this as a starting point limits you a lot to the tube sizing which isn't ideal and if you change that you need to change fittings and you still need to add another rad.... So, it's better to make one yourself unless you are cooling just CPU. Laing pumps are great, a DDC or D5 will server you well and I do have a soft spot for Alphacool radiators
e) If you buy the aforementioned kit, add another radiator plus another two fittings for that rad as well as fans you could be looking at $350-400(Australian pricing) whereas a full custom loop which will likely work better could cost $350-$500 depending on how crazy you want to get while still being reasonable. It's up to you as to whether the potentially 30-40 degree drop over stock is worth it, although you're likely to see 20. A lot of people watercool just for aesthetics and silence
