1 rad up top, the max length the 750D can support.
1 Res/pump combo.
This should be all you need in terms of cooling. Basically, you take the res->GPU->rad->CPU->res. The reservoir is going to bring the temps down just as much as the rad because the water is sitting still in a container basically, which allows it time to get back down closer to room temperature. Thats about all the knowledge I can offer.
BTW, welcome to the forum! Add your rig to your sig, tutorial in my sig.
I agree that you should definitely do a lot of research before starting, but let's not scare away the newbies
If you have basic DIY skills and feel up for a moderately challenging project that will require some thinking and planning, you shouldn't have any problems with a full custom loop. Plenty of people go custom as their first loop (including myself). It's pretty much like anything, if you mess things up, you messed things up, so don't do that
Considering the expense involved, I think it makes sense to go for the loop you'll be happy with now instead of coming up short of what you really wanted. But getting back to the research part, you probably won't be in a position to make the choices to decide what you want until after you've read through a bunch of build logs, reviews, etc. etc.
People come to watercooling for essentially three main reasons: aesthetics, performance, and silence. A good first step in deciding what components you will want would be to figure out where you stand on each of those three factors.
So my main suggestion for the OP, since it sounds like you might be at the very start of your research into watercooling, is check out some of the tutorials here (stickied in a thread at the top of the watercooling forum main page, although some of those might be getting a little old at this point), and look through some build logs. The build logs in particular are excellent ways to get a sense of the process as well as gain inspiration for how things can look when you're done.
Here are two very well-regarded review sites you can also check out which will give you some good technical background: www.martinsliquidlab.org
, and www.skinneelabs.com
I should point out also that a reservoir is NOT a substitute for a radiator. You might get a very small amount of ambient heat loss just the same as when you put a glass of warm water on the counter and eventually it goes back to room temp. But that's negligible compared with the heat your rad will dissipate.
