For a first timer, I would recommend a Rasa RX (or RS if you can't fit a thicker rad)360. Simple all in one solution that isn't a self contained kit (H80 or so), so you can personalize it.
I would go with the Hydrocopper, the block is already attached, and you don't have to worry about getting a non-ref design that can't support a block, or finding a block for it, so on and so forth.
If you get the Rasa kit, get better tubing, and get extra fittings for your videocard if it doesn't come with it (and even if it does, doesn't hurt to have extra).
I'm kind of scatterbrained...I know what I want to say but sometimes it comes out...different...then it sounded in my head. If you need me to explain more, feel free to ask.
For good tutorials on watercooling, watch some Dazmode on youtube. Can be a little hard to understand at times, but he's very informative.
