First of all, if you want to learn about water-cooling than I suggest reading this. It has all the basics and some more advanced information on watercooling.

If its your first time water-cooling (the H100 doesn't count really), then a pre configured kit is probably the best option. Something like an XSPC Raystorm kit would be a good start. That will give you everything you need to set up a CPU loop, and being a kit rather than a unit, its upgradable as you can just add things to the loop.
Of course, you can always drop into the water-cooling forum and ask for a good fully custom loop for your purposes (I advise doing this even if you go with the kit, just to run it past some more experienced eyes than mine). Just make sure to read the guide I linked above, as that will be the first question they ask of you.
Just like with the rest of the computer, educating yourself will help towards making a reliable loop. On the most basic level, knowing how to put on clamp/compression fittings and leak test properly. Medium, knowing that you can fit 7/16" tubing on to 1/2" barbs for a very tight fit. On the higher end then you know that you can use a hair dryer to heat shrink the tubing to the barb. Lots of little tricks you can use to make sure it wont leak.
Pictures should be easy to find, just look up watercooled PC into Google and there will be plenty. Looking up your case name and watercooling will most likely find others who have watercooled in your case, so you can get a general idea of how things will look.
Here the build guide I did when I installed my water-cooling loop.

Just a tip, include a T-Line or a drain valve into the loop right from the start. Otherwise its going to be very difficult to drain the loop later and will require pulling apart some aspect of the loop. I didn't think of this when I got mine and its biting me in the arse whenever I have to maintain or upgrade it, fully intending to get one soon.
